UHPC Transport with mixer truck

Over 60 tons of UHPC concrete were mixed by our customer in a mixing plant last month and transported
to the construction site by 9 cubic meters truck mixer. The driving time took 35 - 45 minutes and the pouring of the forms another 10 - 15 minutes. According to our customer, the flow properties of the UHPC concrete were very good during casting. It required very good flow properties because the casting mold was very complex in geometry and bubbles should not form in any case. The compressive strength achieved was 190 MPa. The customer's requirement was 175 MPa.

Brazil UHPC Wear protection lining of a BF Top Gas Cleaning system

 BF Top Gas Cleaning

The Paul Wurth gas cleaning system for the Thyssen Steel Brazil furnace was one of several Paul Wurth gas cleaning systems we supplied with UHPC wear protection complete the wear protection. The installation was carried out by a local installation company.

We installed the anchors directly at the steel construction company. The UHPC wear protection lining was then lined on site at the steel mill in the installed condition. The total lining area was approximately 1200 sqm. The layer thickness was specified by the plant builder from 25 mm to 40 mm depending on the area in the cyclone. 

    

UHPC Mortar 2000 HT was specified by our customer as the wear protection material. UHPC Mortar 2000 HT is enormously wear resistant even at continuous temperatures up to 1200°C. The cyclone should have a normal average operating temperature of 400 - 500°C. However, it is possible that hot gases up to 1000°C may enter the cyclone uncontrolled from blast furnace.

 

The planned service life is at least 10 years. During these 10 years the blast furnace will not be stopped and therefore repair of the cyclone will be possible only under very difficult conditions.

UHPC HT lined Blades /guide vanes for a Paul Wurth cyclone in a steel plant

Once again we supplied blades / vanes for a Paul Wurth dedusting cyclone. Over the last years we have manufactured and delivered more than 210 blades / vanes of different sizes. We delivered for new projects or for spare parts supply.
The blades are lined on both sides with 25 mm thick UHPC HT (high temperature resistant UHPC). 

Each delivery is extensively tested by us. 

It has been proven over the years that the blades manufactured by us can withstand the maximum loads in a blast furnace dedusting for years.

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.

High temperature resistant UHPC pavement

Constant very high temperatures and high
loads cause high damage to stone or concrete
floors.
Last year we re-lined a floor in the steel collis
warehouse with UHPC HT. The freshly rolled
steel collis have an average weight of 20 tons
and are still more than 280°C / 536°F warm
for a few days when they are stored. The
radiant heat has caused massive damage to
the floor area in most areas of the hall. In
addition, the hot collis are driven from the
rolling mill into the warehouse with special
forklifts and placed correctly.

The routes in the warehouse had to be
completely renovated for safety reasons.
Since the ground was so bumpy, there was
a risk that a forklift with the hot colli might
fall over.

For this reason, the old floor was completely
removed. The subbase floor was rebuilt and
carefully compacted. Subsequently, at least
50 mm /2 inch thick UHPC HT high temperature
resistant flooring, which also has a very high
compressive strength and wear resistance, was laid.
In the UHPC HT floor covering, two-layer
reinforcement was introduced in order to absorb
the shear stresses that are generated by the heavy
forklift movements.
We relined approx. 1000 sqm hall floor.

Companies which used UHPC Wear Protection in the last 25 years

 

We are always asked who has been used UHPC
Wear protection for the past 25 years. WPE DK our UHPC wear protection specialist, took the task to compile a list of companies who used UHPC as wear protection during these years.

The list includes plant system supplier and plant operators in
worldwide. The list should give an impression of where
UHPC is already standard as wear protection everywhere. In
In many cases, plant operators have the UHPC material
installed by own fitters.

Here is the list:
The company names can change over the years and some
companies probably have merged with other companies.

UHPC wear protection an example from the steel industry

BF Top Gas Cleaning

UHPC has been specified as a wear protection material in a new dedusting cyclone for a blast furnace by one of the world's largest plant manufacturers in the steel industry. 

We installed the anchors directly at the steel construction company. The UHPC wear protection lining was then lined on site at the steel mill in the installed condition. The total lining area was approximately 1000 sqm. The layer thickness was specified by the plant builder from 25 mm to 40 mm depending on the area in the cyclone. 

          

UHPC Mortar 2000 HT was specified by our customer as the wear protection material. UHPC Mortar 2000 HT is enormously wear resistant even at continuous temperatures up to 1200°C. The cyclone should have a normal average operating temperature of 400 - 500°C. However, it is possible that hot gases up to 1000°C may enter the cyclone uncontrolled from blast furnace.

 

The planned service life is at least 10 years. During these 10 years the blast furnace will not be stopped and therefore repair of the cyclone will be possible only under very difficult conditions.

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.

What about the claim that a UHPC essence, local cement and local sand can be used to produce UHPC concrete?

Again and again we read in flyers from UHPC manufacturers that they have a UHPC essence with
which the customer can easily mix a local cement and local sand with this UHPC essence and water and then the customer gets a UHPC concrete. As a rule, this text is very general and does not go into technical details, which has its reasons.

Let's start with the statement:
...locally available cement and sand can be used....

In itself, this statement is not wrong, if we disregard what the customer expects from the quality.
Why?
Well, if we buy a C25 cement, it is impossible to produce a C100 UHPC concrete with a UHPC essence.
If we want to produce a high quality UHPC concrete we need high quality cement, this cannot be changed.
Many users believe that cement from manufacturer A is exactly the same as from manufacturer B if only it says C35.
This is also partly a misconception. Yes, it is true that with both you will get a strength of 35 MPa. But if you look at the anlaysis of the two cements, they could be very different. However, these differences determine the suitability for a UHPC and how it can be processed.
The same applies to aggregates such as sand. Of course I can add local sand but a high quality binder will only be a high quality UHPC if the right sand with the right grading curve is added, otherwise there is a possibility that you will only get a good concrete.

You can of course test the local sand and cement for suitability. Such a test takes one day if the analysis data of the cement and sand are available. We do this cost free for our customers.

Who invented the UHPC Binder?

Again and again we are asked who invented the UHPC binder. Very often the French and the Germans are associated with it, but all these countries and their companies did not invent it. It was the Danes and everyone else copied the Danes. Why we want to know this so exactly. Well, our whole team worked for this Danish company. We have a timeline here of how it all came about.  We at hhbc-consulting and WPE DK have been working with UHPC for almost thirty years. Who can have such experience.
