UHPC Earthquake security systems for existing buildings

Ultra High Performance Concrete (UHPC) is a high-strength, ductile material formulated by combining cement, microsilica, fine sand, water, and steel or ceramic fibers and mesh.
The UHPC concrete provides compressive strengths up to 250 MPa / 36200 psi and flexural strengths up to 30 MPa / 4300 psi.
The ductile behavior of UHPC is, with the capacity to deform and support flexural and tensile loads, even after initial cracking. 



 
Façade elements made by UHPC, protect people and vehicles in an earthquake against fragments litter in building structures made 
of concrete and brickwork.

Concrete ceilings are rigid and brittle structures that at the an earthquake stress the concrete structure can break partially. The fracture is not 
a slow phenomenon under load - the fracture occurs when overloading on suddenly.
The result is that to loosen individual fragments of the ceiling could (fragments litter) fall on machines or people. Are the fragments large enough, it can lead to complete component failure.

UHPC prefabricated ceiling structures prevent like a prestressed network the fragments become loose during the quake from the ceiling.

People and machines are protected by such a suspended ceiling construction.

Emergency exits can win with such additional structure several times of safety.

Just as concrete ceilings and concrete columns are complex constructions an essential safety feature of a quake. The concrete columns must take tremendous 
flexural and compressive forces. A chipping of the concrete structure of the inner steel reinforcement would have a very rapid component failure result.
Concrete columns can by a jacket (by shedding) of UHPC gain much stability and carrying capacity. A chipping of the concrete structure at a load by an earthquake of small and medium thickness is almost impossible with the appropriate cover. 

Advantages of UHPC
  • Extreme high compressive strength
  • High flexural strength
  • Extreme low porosity
  • Extreme good flowability
  • Fast increase of compressive strength (min. 70% after 48 hours)
  • High wear and impact resistance
  • Absolute frost and thaw resistance
  • Impermeable to fluids but still vapour permeable
  • Anticorrosive features
  • Good bonding to sub-bases, aggregates and reinforcement
  • High temperature resistant
  • Jointless lining
  • Usable as mortar, grout and spray
  • High ductility in combination with fibres or nano fibres
  • Usable with standard concrete tools

UHPC - His entry before and after a quake

UHPC materials can be used as additional safety in new concrete structures such as buildings, bridges, etc. For existing buildings and very old buildings, targeted activities involving the use of UHPC materials can significantly increase the safety of people and buildings. With UHPC materials, damaged buildings can be repaired to restore their old stability or improve their stability against earthquake loads by improving their building structure.

Possible applications for high quality UHPC materials

Repairing
To make existing structures safer for future earthquake

Retrofitting
To upgrade the earthquake resistance up to a level of  the present day codes by appropriate techniques

Strengthening
To upgrade the seismic resistance of the a damage building

Rehabilitation
Reconstruction or renewal of a damaged building to provide the same level of function, which the building had prior to the damage

Restauration
Rehabilitation of buildings in a certain area

Remoulding
Reconstruction or renewal of any part of an existing building owning to change of usage or occupancy

Example of retrofitting techniques
  • Minor cracks
    Repair by injecting UHPC
  • Buckled longitudinal reinforcement, broken ties and crushed concrete
    Replacement of new reinforcement welded with existing bars and new additionally closed ties were placed, UHPC concrete with low shrinkage properties installed.
  • Severely damaged columns adjacent to added walls
    Retrofitting with encasing in UHPC concrete with appropriate longitudinal and transfers reinforcement.
  • Other columns
    Retrofitted with wire mesh and cover with 50 mm UHPC concrete by spraying or casting
  • Existing masonry walls
    Are retrofitting by using wire mesh and 30 mm of UHPC® mortar or spray

Like concrete cover constructions, concrete columns are also essential safety aspect in a quake. The supports have enormous bending and compression forces to take. 
A spalling of the concrete structure from the internal steel reinforcement would have a very fast component failure result.
As with the concrete floors, columns can be replaced by a grouting UHPC gain significantly in stability and carrying capacity. A flaking of the concrete construction is under load from a quake of small and medium strength with 
appropriate sheath almost impossible.

In a quake will be in the brickwork of a building very quickly showing cracks in the in the worst case, individual stones break loose (Rubble throw) or a whole bandage, which too can lead to a component failure. The cracks in the masonry after a quake are permanent and can become one uninhabitability and demolition of 
the building to lead.
Damaged masonry will be repaired differently depending on the degree of damage.
Fine cracks can be filled with UHPC injection methods. Loose masonry, bad mortar can be increased by new masonry and UHPC mortar substantially in the strength and bending tensile strength. Masonry can also be improved in its entire surface with a fibre reinforced UHPC layer in combination with steel or fibreglass reinforcement substantially in its static structure. Especially glass fibre or carbon fibre reinforced 
UHPC show a high ductility.

In any case, should structural modifications such as those described here, be agreed in consultation with 
an architect, stress analysts and the competent local planning authority.


Sand for civil construction is running out in many places of the world - Solution UHPC Desert Sand Binder + Nature Desert sand

Sand consumption today

In more and more parts of the world, the availability of sand is becoming increasingly difficult or even impossible for the construction industry.
Gigantic sales are now being made with sand.
Millions of tons of sand are transported to the oceans each year, and demand will continue to rise.

Example
  • Over 47 billion tons of sand are mined annually
  • For a standard house you need approx. 200 to of sand
  • For 1 kilometre highway you need approx. 30000 to of sand
  • Global sand business is 70 billion US Dollar/year



Types of sand extraction

  • Sand mines
  • Sand from rivers
  • Beach Sand
  • Sand mining in coastal area

 

 

WPE DK is manufacturer of UHPC Desert Sand Binder for more than 10 years. This binder system is mixed only with desert sand and a little water. Now there is the 3rd development stage of UHPC Desert Sand binder. This new generation differs significantly from the 1st generation in strength, workability, sustainability and much lower CO2 footprint. The latest generation can also be produced on site with local raw materials without any problems.

UHPC Concrete tower construction up to 300 meter

Industrial chimneys and lighthouses have always
been bricked up, and so well that they are still
fully functional to this day and would be a while
if they weren't torn down. Today you would not
be able to pay for such a construction method
and you would no longer have the time to assemble
it.

Large or tall towers such as TV towers, radio masts,
offshore / onshore wind turbines and similar
structures are made of steel or reinforcing concrete.
High-quality UHPC materials can take on
compressive strengths of more than 240 MPa /
34.800 psi and thus corresponding bending tensile
strengths without reinforcement.

With appropriate reinforcement, these values ​​can
be multiplied several times. Today, slim, high-
strength tower constructions are possible that
cannot be achieved with standard concrete. The
main tube construction of radio masts can also
be made entirely of UHPC today.
Towers for onshore and offshore wind turbines
are already made from UHPC prefabricated parts
or cast on site.

UHPC has many technical advantages over steel
or reinforced concrete structures. UHPC towers
are absolutely corrosion-resistant, quickly
installed and maintenance-free.
 
 

30 years of fundamental difference between UHPC and concrete

This photo is more than 30 years old. It is from the first flyer I used to sell UHPC. The photo was meant to explain to our customers what the general difference between concrete and UHPC is, because almost all of our customers at that time had no idea what the difference between concrete and UHPC is. At the time, I found this photo comparison brilliantly simple and clear.

Today, after 30 years, our team still has the feeling that many write and talk about UHPC but really do not recognise the basic difference. On the contrary, people today try to dilute and obfuscate the difference between concrete and UHPC. For these professionals, everything and nothing is concrete and UHPC. There are very few professionals who can explain the difference in simple and logical language. However, the architect, the structural engineer or the construction company must know the difference in order to be able to use both materials optimally.
For this reason we have decided to bring out this very old photo and to try again to explain the difference between concrete and UHPC and hope that some interested people out there will follow us, to whom we would like to thank already now.



The idea behind this photo was to produce two test cylinders and subject them to a pressure test. The main point was not to find out which material has the higher compressive strength, that was clear from the beginning.
No, we wanted to show and compare the fracture surface. This fracture surface shows the difference so simply and clearly.
At the beginning we mixed a standard cement binder and a UHPC binder and added the same grading curve and material quality to aggregates, filled them into test cylinders and waited 28 days. After 28 days, the concrete and UHPC cylinders were demoulded and pressed in a press until they broke. The result of this fracture can be seen in this photo.


The left cylinder is the standard concrete cylinder and the right cylinder is the UHPC cylinder.
Looking at the left cylinder, the fracture surface is clearly in the binder, the gravel aggregate is not broken. The weak point in this case is the cement binder.
If we look at the right cylinder, the fracture has gone through the gravel aggregate and the UHPC binder simultaneously and evenly. There is no weak point here. The UHPC binder is just as hard and resistant as the aggregate and the adhesion between aggregate and binder is extremely high.


This photo comparison and the resulting result shows that there are two fundamentally different binder systems, the concrete binder and the UHPC binder, whereas the UHPC binder is superior to the concrete binder by several times. This is how it was then, how it is now and how it will be in the future.

Heat problems on airports

The climate is changing, the summers are getting much hotter. The summers are getting so hot that
infrastructure constructions such as concrete roads and asphalt roads are reaching their limits. Here is one of many examples, airfields. The taxiways, aprons and parking areas have to be cooled with water because the pavement may reach its load limit. Costly and time-consuming repairs are the result. The heat waves are getting longer every year.
Wouldn't it be an improvement to use semi-rigid floor coverings with a temperature resistance of up to +90°C and very high load-bearing capacity in highly stressed areas? An alternative would be UHPC TopLayers that do not lose their peak load-bearing capacity even at very high temperatures.

Comparison Sand for the construction industry - Alternatives to Sand for the construction industry

 The global construction boom is continuing and will not decrease significantly in the future. climate change is forcing new constructions. Old constructions have to be replaced. Most of the world's major sites are on the coasts, and constructive coastal protection will buy these sites some more time, but the major sites will also have to change in terms of construction technology. Concrete as a building material is needed for this transformation.
Sand as part of this needed concrete has become a big problem. The gigantic demand leads to a lucrative trade business worldwide, which permanently destroys the nature of the coasts and rivers.
Several years ago we pointed out that with the UHPC technology it is easily possible to replace a very large proportion with recycled sand. Only these recycling plants for construction waste are rarer to find worldwide than diamonds. And yet, the expansion would be an extremely lucrative business, also for investors.
The fastest way to drastically reduce the current demand for sand is to use desert sand. For several years now, it has been possible to easily produce concrete from desert sand that is much stronger and easier to handle than standard concrete. If one were to calculate the current worldwide sand consumption as a standard, the desert sand of the Sahara would last about 100,000 years.
Even if the entire global construction industry still finds it extremely difficult to use desert sand, which there is actually no reason to do, development will force them to do so. For investors who become active now, this will be a gigantic business in a few years.

CNN Article - It´s so hot, roads are buckling, they are putting foil on a bridge and roof....

 The climate has changed and even if all countries of the world would reach their climate goals, it would still take decades positively estimated until the climate change would move again in another direction. So we and the next generation of us have to live with the changes like heat. Now the architects are asked not to build beautiful glass palaces but buildings that resist heat. Take a look at the traditional building constructions in Africa and the Arabic countries and learn quickly. Our learning about building materials started years ago. We have a strong base in southern Africa. We learn and develop HPC and UHPC based on local raw materials and we combined our HPC and UHPC systems with local construction materials.
Many of our HPC and UHPC binder systems are high temperature resistant and may be easy to work with under higher ambient temperatures in the future.

UHPC concrete meets aesthetics

UHPC Ultra High Performance Concrete offers designers and artists completely new design possibilities. Whether as a binder system or in combination with metal, fibre or textile reinforcement, there are no limits to the creative and constructive imagination.

In addition, it is very easy to process, whether as mortar, casting compound or shotcrete. Anyone can process our HPC and UHPC material. We can also modify the HPC and UHPC mortar material structure according to the customer's wishes, whether as a fine clay structure or a coarse clay structure or plaster structure.
Sculptures or constructions made of HPC or UHPC are also long-term resistant to even the most extraordinary environmental conditions. HPC and UHPC concretes can also be used under water. They are absolutely waterproof from a layer thickness of 10 mm.

The advantage for designers
    - Thin, filigree structures of very high strength
    - Large-scale elements in a cast thin-layer structure.
    - HPC and UHPC can be combined with almost all materials in a new way.
    - Very smooth or extremely fine surface structures can be achieved with HPC and UHPC
    - UHPC is several times more resistant to chemical attack than any standard concrete.

We produce all HPC and UHPC material qualities as mortar, casting and injection moulding compounds.

UHPC concrete meets aesthetics
In the living area as well as outdoors


    Concrete bowls
    Lamps made of concrete
    Outdoor furniture
    All kinds of pool or whirlpool designs
    Garden design elements such as stones, tiles, etc.

Standard concretes have a natural surface with an open-pored structure. In contrast, UHPC concretes also have a natural surface but without a porous structure.
Due to the very high material quality, our HPC and UHPC products require very little or no maintenance. The life expectancy of design objects made from our products can be
can easily be assumed to be +100 years.


UHPC concrete meets modern extraordinary lifestyle

Here we develop and produce special and extraordinary binder systems for the design of unique pieces on customer request.

Here, special HPC and UHPC binder systems are produced from sustainable raw materials from all over the world, which are then combined with exceptionally rare or expensive materials at the designer's and customer's request. The end product is then unique and cannot be copied and is very, very expensive.

UHPC Ultra High Performance Concrete in local Asian architecture

UHPC Ultra High Performance Concrete is barely considered in modern Asian architecture, although this material is over 25 years old. 

HPC and UHPC concrete is not just a concrete, it is something special. In the beginning, 25 years ago, we broke one strength record after another. We have done extreme constructions and linings and cold and heat.
For the last 15 years, we have been focusing on sustainability in the Asian market with our HPC and UHPC materials, using local materials. We can perfectly combine our materials with local construction materials such as bamboo. The result is a unique, sustainable, cost effective material or construction. With our HPC and UHPC binder systems, we can incorporate almost any local material. We can work with local architects and contractors to create buildings and structures that can withstand floods, fires, storms, earthquakes and insect attacks. We also want to learn with local
builders how we can work together to create permanent floating platforms for living on the water or on the coast.
 
Yet this extraordinary material offers a large number of answers to the requirements of modern Asian architecture.

Corrosion
HPC/UHPC materials are very good corrosion resistant. Old concrete, wood or steel structures can be easily and inexpensively repaired and made usable for many decades.

Waterproof
HPC/UHPC materials are waterproof from a layer thickness of 10 mm. Houses can be made resistant to
flooding so that they can be quickly cleaned and used again after a flood.

Seawater
UHPC materials are absolutely seawater resistant. HPC/UHPC can be processed underwater. This means that jetties can be repaired easily and quickly. they can then be used again for the next 50 years.

Rotting
UHPC do not rot. Wooden structures that are already starting to rot or are damaged can be quickly and permanently repaired with HPC/UHPC.

Material Strength
HPC/UHPC materials reach strengths from 20 MPa to 240 MPa

Steel structures
HPC/UHPC materials can permanently replace steel structures and require no maintenance

Earthquake
HPC/UHPC materials offer solutions to increase the seismic safety of existing buildings

Temperatures
HPC/UHPC materials are extremely temperature resistant from -90° to +1200°C. An ideal material for facades

Design
With HPC/UHPC materials it is possible to achieve extremely fine surface structures

Processing
HPC/UHPC can usually be processed like standard concrete. We produce HPC and UHPC castable,
mortar and shotcrete versions.
HPC and UHPC materials help to drastically reduce the concrete requirement / weight.
HPC and UHPC sheathing of steel or wooden structures standing on or in the water, will permanently protect the construction against rotting.
Of course, UHPC can also be used to repair buildings and floors easily, quickly and effectively.

There are many other arguments for the use of UHPC in Asian architecture.
We are happy to be of service to every designer, architectand contractor with our decades of experience.

At the moment we are producing our HPC and UHPC materials in Europe. However, we plan to build one or two production locations in Asia in the near future.

UHPC concrete with rubble or demolition material

Building rubble or demolition material is a very valuable raw material today, its reuse (upcycling), in our opinion, a very important step for sustainability, reduction of raw material requirements, energy reduction in production and reduction of CO2.


Many architects and designers already work in their designs with materials that have become interesting building materials again through upcycling. Old makes new.

 

In Europe there are more and more companies that have specialized in the processing of used building materials. You are preparing demolition material for a new use in your own plant or already on the construction site. The demolition material is sorted and broken according to quality and color.
In conjunction with our HPC or UHPC binder systems, old building materials obtained through demolition are transformed into interesting new building materials with amazing properties.
The sorted and broken waste material is processed with an HPC binder material for later use as an aggregate in a very simple work step. After processing, the demolition material is suitable for processing with HPC or UHPC binder material and water into high-quality concrete, mortar and floor coverings. Plastics, rubber, porcelain and glass can also be processed as aggregates.

With HPC or UHPC casting binder systems, prefabricated elements or bricks can be produced.

New floor coverings can be produced from milled asphalt road surfaces in a few simple operations. This
processing process could be carried out directly on site with the appropriate screening and mixing machines.

Living and working on water and under water with UHPC as construction material

Since than 30 years, UHPC Ultra High
Performance Concrete has been used
worldwide in the offshore sector as
a foundation, repair and construction material.
In offshore wind power technology, UHPC
is used as a floating foundation construction.

Deep sea constructions with UHPC have
also been successfully tested down to a
depth of 3500 m / 11480ft. Together with a  
German university, we tested dome 
constructions with different concrete 
qualities and UHPC. Only UHPC was able 
to withstand the enormous water pressure.

Likewise, energy storage systems for
offshore wind turbines are currently being
developed, which consist of hollow concrete
balls measuring over 30 m in diameter,
which are sunk to a depth of 300 m. These
energy storage systems would also be ideal
for supplying energy to floating cities.

Living and working on water and under water
can be realized sustainably and without an
problems with UHPC Ultra High Performance
Concrete materials.

The first serious projects are already planned
and are about to be realized. International
architect groups are already working on
self-sufficient cities above and under water.
UHPC is an important building construction
material for the designs, which are designed for
extreme longevity with very little to no
maintenance.

The advantages are
  • Absolute seawater resistance
  • Extreme corrosion resistance
  • Extreme compressive strength
  • Extreme tensile strengths
  • Almost any design geometry can be made
  • Material combinations of all kinds are easily possible
  • Installation methode same as standard concrete

Machining UHPC concrete like metals

UHPC is a very unusual material that is still
far too little considered by architects and
designers. It is still viewed and processed
like a normal concrete.
Our view is more that we design and
manufacture UHPC to treat it more and more
like metal. UHPC in the right quality can
already be machined with tools from the metal
industry. Very high accuracies can be achieved
here whether in surface processing or in shape
processing.
The surface treatment can either be carried out
using special UHPC casting molds or by
identical processing steps as for metals, or
combined casting and subsequent processing.
There are no limits to the design options here.
In terms of shape, metalworking tools or machines
can be used with the same objective as metals.
Architects, designers and artists have not even
used a fraction of the technical possibilities.

One example is the use of computer-controlled
water jet cutting machines. For a customer, we
should test the possibilities of making special
bevel cuts as plate slots that cannot be cast in
this way. Additional cutting tests were carried
out to check which geometries can be cut and
what minimum wall thicknesses can be achieved
between the individual cuts. With the right
combination of UHPC binder, unit quality and
setting of the cutting machine, amazing results
can be achieved. The tested UHPC plates had a
plate thickness of 15 - 25 mm, no metallic
reinforcement and were dried for 48 hours in
normal ambient temperature before they were
processed.

With the UHPC binder-aggregate combination
used in the test, cutting distances of 5 mm could
be achieved.
As soon as possible, further cutting tests will be
carried out with UHPC desert sand binders.
Water jet cutting enables complete "images" to be cut in UHPC panels or special construction elements.
With this type of material / machine technology, it is possible to produce a large number of facade panels with an elaborate cut design at low cost in a short time.

Recycling of old building materials with HPc and UHPC bindersystems

In our fast-moving times, old houses, some of
them historical houses, are being brutally torn
down to make room for new, more modern,
larger, higher and often not more beautiful but
more effective new building designs. Very
often there is no time left and there is often no
will to secure the valuable and reusable old
building material.

The end of an old building is a heap of rubble
that is only suitable as gravel material for the
subbase material of streets.

The architects in particular could campaign
for the reuse of such materials. It would be
entirely possible to reuse these old materials
in modern design concepts and to save some
valuable raw materials.

This year we will start some attempts to
combine UHPC with a variety of old used
materials. We are very sure that this is
possible without any problems, both in terms
of statics and construction. Of course, with
UHPC we can copy old materials in
appearance and design extremely precisely,
in some cases this is certainly sensible and
necessary. However, we want to reuse old
materials and hand them over to a new
design function. Even building rubble could
become a very interesting concrete material
in combination with UHPC. We also want
to give architects and designers new design
options using old and ultra-modern materials.

Recycling of UHPC concrete compared to standard concrete

Our UHPC concretes are far superior to standard concretes in all technical properties and actually
make them a competitive material for steel. Also in this comparison, UHPC concretes have advantages such as corrosion resistance and temperature resistance, etc.

UHPC concrete constructions achieve a multiple service life of standard concrete in comparable constructions. This means standard concrete structures are demolished much faster and the debris has to be recycled. The demolition material is used as gravel. It is currently trying to recycle this demolition material as a building material.

In addition to a longer service life compared to standard concrete, UHPC also has many advantages here.

1. UHPC concrete has a very high compressive strength which is similar or better to many standard aggregates of standard concrete.

2. UHPC concrete granules have no to extremely low porosity. Thus, UHPC Granules does not absorb very little water.

4. UHPC concrete granules are corrosion and seawater resistant. UHPC concrete granules can be easily processed with standard concrete or UHPC concrete.

6. At the moment we are working on trying to prepare standard concrete material granulate, so that it can be used as a fine aggregate for some UHPC grades.

7. We also plan to use recycled UHPC high temperature material. It could very well be used as aggregate for UHPC HT or for refractory materials.

UHPC Desert sand binder - Local Concrete for Africa

Almost four years ago we developed a UHPC Desert cement binder to process desert sand into a concrete with very high strength values. Only cement binders, water and desert sand are necessary for this. For mixing a standard concrete mixer is needed. The focus of binder development two years ago was on the professional construction industry.

In discussions with architects and organizations operating in Africa we were asked, if we could develop a simple, not so high-quality version of this binder that can support the traditional simple
constructions of the rural population. After some
discussion, a list of requirements for this new
binder was created with which we now work in
our lab. UHPC binders were originally developed
with the aim of achieving an extremely high level
of strength. Then we discovered with our UHPC
binder the incredible combination possibilities
with a variety of natural materials.


Our UHPC binders can perfectly support or
replace wood, straw, loam and clay constructions in terms of their strength and resistance to high
UHPC can also be easily combined with recycled material. It can be made of furniture and sanitary equipment. UHPC concrete is not flammable, which contributes to the safety of the accommodation.

The aim of our current binder development is to
drastically reduce binder costs, to keep the
mixing procedure as simple as possible, to
drastically reduce the proportion of binder in the
overall mix, to reduce possible material transports,
to enable new material combinations with local
raw materials and to preserve as many
properties of UHPC as possible, temperatures and high solar radiation. UHPC binders are completely waterproof, even in very thin layers, do not rot and provide safe protection against termites.

There is also the possibility to use local cement for the production of UHPC Desert Sand Binder in addition to the local desert sand. For this we would have to test local cements for their suitability for our UHPC binder.
