Use of UHPC HT construction material in extreme fire temperatures

20 years ago we started as the only one in the world to use high temperature resistant HT UHPC in areas
up to 1200°C / 2192°F. We use this material under the most extreme wear and temperature conditions in industry. High temperature resistant UHPC HT can be used as construction material, radiation insulation, floor material, wear protection and corrosion protection.

We produce this material in several qualities as mortar, castable and shotcreate.

Constructions made from our UHPC HT material can withstand very high temperatures for a very long
time. Steel and concrete structures are protected in steel plants, power plants, offshore platforms, civil construtions, refinery, chemical plants etc. with UHPC HT material.

A few years ago we started to develop UHPC HT materials for architectural applications. Today residental housing constructions can be built for example to withstand wild fires and fire storms for long period of time. There are already the first companies that want to manufacture doors and window security systems from UHPC HT. If windows and doors were to be secured against high temperatures, a fire from outside would have no way of penetrating the house.

These high-temperature UHPC HT are also available with mixed thermal insulation.

In public buildings, escape routes, stairwells and supporting structures can be secured against fire and destruction. UHPC HT can be processed in the same way as normal concrete.

UHPC HT is not only extreme fire-resistant and thus protects life, UHPC HT has a very high load-bearing capacity, no water can penetrate UHPC HT constructions at flooding
situation, UHPC HT can be perfectly processed as a tilt-up and precast construction and is absolutely resistant to all types of fungi and termite infestation. UHPC HT has also been used in the military and in security technology for many years.

UHPC Floating platforms

The future will take place more and more on the water of the oceans, whether on the coast or in the open sea. UHPC Ultra high Performance Concrete will play a crucial role in this. The two main construction materials in the offshore sector so far are steel and concrete. However, both have significant disadvantages compared to UHPC.
On the one hand, there is resistance to salt water. Steel is very difficult to protect against corrosion and even then the construction still has to be serviced regularly and very time-consuming and expensive. Floating structures should have a lifespan of at least 100+ years in the future.
With normal concrete structures the problems are similar, if not more serious. Once extremely corrosive seawater has penetrated the steel reinforcement unnoticed, the repair effort is enormous. In addition, for this very reason, the construction must be extremely thick-walled. An anti-corrosion coating makes the entire construction additionally expensive and here too the entire construction must be checked regularly in short periods of time.
Special UHPC concretes have extremely high strength values ​​compared to normal concretes, they are waterproof after a wall thickness of a few millimeters and are absolutely salt water resistant. Some of our UHPC binders are also extremely temperature-resistant (up to max. 1200°C) and they are very good wear-resistant (resistant to wear and tear caused by moving ice floes). Due to the high strength values, structural elements can be optimized or minimized in terms of size and weight.
UHPC concrete will be the much cheaper material for the required service life.

As developers and producers of high-quality UHPC binder materials, we want to focus on three future projects:

1st project
Floating work platforms for energy generation and storage.
All the major offshore wind farm operators worldwide are currently planning not only to generate energy with wind turbines, but also to use this energy to produce hydrogen on site in the wind farm. Solar systems on the platforms should contribute to additional energy generation. The platforms can be manufactured in several standard segments and connected to form a network at sea. These platforms can be made from very lightweight UHPC. This UHPC material can be self-floating.

2nd project
Floating living and working platforms, artificial islands for the coastal area and for the open sea. Platforms
for residential buildings, hotels, schools, hospitals, office buildings and production facilities.
Please see the corresponding article below.

3rd project
Offshore missile launch sites
There are various ideas for implementing this. In Germany, launch sites on ships for small and medium-sized rocket systems for satellite transport are being considered and are already being planned. Elon Musk is planning rocket launch sites for converted former oil production platforms. In all of these plans, UHPC could contribute to intelligent, lasting solutions. Ships were built from UHPC more than 20 years ago and
offshore platforms with UHPC were significantly improved structurally and statically.
Please see the corresponding article below.

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

HPC and UHPC test material and samples

Very often we are asked for standard HPC and UHPC test material or HPC and UHPC standard samples by our customers. But we don't have any standard patterns. An example will explain why this is so.

The HPC and UHPC materials developed and produced by us are used in architectural fields such as

• Facades
• Building structure
• Waterproof basement structures
• Roof structures
• Balcony constructions
• Garage constructions including floor coverings
• Bathroom interior
• Bedroom interior
• Kitchen interior
  
• Office interior
• Stair construction
• Tiles for walls, floors and ceilings
• Pools
• Open fireplaces
• Lamp design
• Furniture design
• Safety constructions
• Fire protection
• Wall plaster
• Floor coverings
• Earthquake protection
• Flood protection
• Walk-in safes
• Panic rooms
• Water term
• House boats
• Sewage systems
• Concretes made from recycled building materials
• Concretes with Co2 neutral aggregates
• Concretes for floating and subsea constructions
• Materials for the renovation of historic buildings
• Bridge constructions
• Floating constructions

There are 216 standard colors + probably just as many structure
variations + probably even more aggregate combinations.

Each user of our materials such as precast concrete plants, designers, construction companies, etc. have their own standards and standard samples.

However, if you cannot find what you would like for your project from the processors, we are very happy to help you. You just have to give us very specific details about what you want. With your specification we will make a sample for you.

I have to give you the same answer for the HPC and UHPC material samples for technical tests. We don't have any standard materials. We have HPC and UHPC materials that our customers around the world like to use, but customers just as often come and give us a technical specification for a material based on HPC or UHPC technology and then we develop this specified material. If the customer is satisfied, the material goes into production.

UHPC Pavements in Multi-storey car parks impermeable and strong

In multi-storey car parks, paricular attention must be paid
to the following

• Constant vehicular traffic
• Chemical attack from oil, petrol and salt
• Rutting from continual driving along the same routes
• Braking
• Wear and tear from concerning traffic
• Spiked tyres
• Repeated freeze-thaw cycles
  

Floors in multi-storey car parks must therefore be able to withstand 

these stresses. Equally important, they must be impereable, preventing 

penetration of fluids or salt.

In designing a multi-storey car park, it is preferable to use a light but strong material to achive the most economical construction possible.

During construction, speed of installation and early trafficking are also important.

The key words for multi-storey car park projects are strength, impermeability and lightness.

 

UHPC TopLayer R (with reinforcement)
UHPC TopLayer R is recommended for particularly poor floor surfaces or for floors subject to high traffic loads.

UHPC TopLayer R is a combination of a special fiber-reinforced UHPC concrete and reinforcement mats.

UHPC Phalt
UHPC Phalt is a semi-flexible floor covering consisting of an asphalt supporting structure and UHPC Phalt binder as a filler. This combines the flexibility of asphalt with the strength and resilience of UHPC concrete.

 

 

 

Advantages of UHPC TopLayer and UHPC Phalt

• Very high bearing capacity
• Reistant to point loads
• Very high wear resistance.
• Minimal requrements for joints
• Impermeable
• Very good chemical resistance
• Slip resistance
• Level and smooth
• Rapid installation
