UHPC concrete for new precast bridge construction or bridge repair

For more than 25 years, UHPC Ultra High Performance concrete has been used for the construction and repair of concrete bridges worldwide. The mechanical and durability
properties are absolutely ideal for modern bridge construction.

WPE DK UHPC concrete is used in the production of precast concrete parts and for on-site assembly. With UHPC concrete, very slim and high load-bearing elements can be manufactured quickly, cost effectively and very precisely. All of our UHPC material qualities can be processed with most types of concrete mixer.

Our UHPC bridge material qualities are usually mixed with a water / cement ratio of less than 0.25 and a proportion of steel fibers. Compressive strengths of 150 MPa / 21800 psi to over 230 MPa / 33400 psi are achieved in our standard quality.

Our UHPC material properties meet all required technical data, including in the USA from the responsible DOTs. All of our UHPC material qualities are subject to a permanent quality check of the raw materials used, finished products and processing on site on the construction site.

We use our UHPC castable materials for joint fill solutions or connection of precast bridge elements. With UHPC castable you can minimizse the connection joints.

We manufacture UHPC mortar, UHPC Castable, UHPC Shotcrete and UHPC Rapid material qualities for bridge construction. At the customer's request, we also develop and manufacture special qualities.

UHPC mortar, UHPC Shotcrete and UHPC Rapid are mainly used for repairs. No extensive preparatory work is necessary for repairs with our UHPC materials. After less than 48 hours, our standard materials reach more than 70% of their maximum strength. UHPC is waterproof from a layer thickness of 5 mm.

We use our UHPC TopLayer or UHPC Phalt material qualities for bridge decks. In Europe we use UHPC TopLayer for new wood bridge construction. All UHPC can be mixed on site and processed quickly and inexpensively with standard processing machines.

The mixing is very simple. You mix 1 part UHPC Binder with 1 part aggregates and clear water, that is all. Everybody can mix it. No additional addives are necessary.

In the future more people will live one artificial islands made by UHPC concrete constructions

In the future, more and more people will be forced to live on the water in coastal and flat islands.

Most of the world's major sites can be found on the coasts of our continents. the space for enlarging the site is not infinite. The first city planners are working on designs for how cities can spread out on the water. In other parts of the world, coastal sites are so deep in relation to the ocean that if the water rises just a few centimetres, the sites are in danger. Some islands are so deep that they also have extreme problems with today's ocean levels.

The previous wooden constructions of the coastal and river delta inhabitants will no longer be sufficient.
Rising sea levels and flooding are the result of climate change.

New construction designs by architects and new construction material can help coastal residents. Likewise, the existing wooden constructions can be made more stable where possible.

WPE DK HPC and UHPC binder systems are able to use local raw materials as aggregates or reinforcement such as bamboo, coconut fibre, jute fibre, shell casing, desert sand, lawa, granite etc. Everything built from HPC and UHPC concrete with such aggregates is sustainable and can be easily reused.

WPE DK HPC and UHPC concrete is ideal as a construction material for repairs and new constructions. HPC and UHPC concrete can extremely increase the stability and service life of wooden structures both above and underwater and create a corrosion protection for steel construction. 

Artificial islands on stilts on the coast or floating
islands on the high seas can offer solutions of any size. The islands can consist entirely of UHPC concrete. UHPC concrete is absolutely seawater resistant and has enormous strength. Entire cities could emerge on such platforms. The first architectural drafts by large international architectural offices have been around for a long time. Disused oil production platforms could also be upgraded and serve as starting points for such large artificial platforms.

For more than 30 years, HPC and UHPC concrete has been used in the international offshore industry as a material for new constructions or repairs. A lifetime of several hundred years is assumed for WPE DK UHPC new
designs.

Artificial, near-natural reefs and bank protections with HPC and UHPC are also planned, whereby the bank protections adapt to nature in their design and are not ugly concrete blocks. HPC and UHPC materials are far superior to steel in many areas in the offshore industry. There are already the first plans for underwater structures made of WPE DK UHPC special qualities in the deep sea down to 3000 m /9800 ft.

Production of UHPC combat binder and concrete under war conditions

For more than two years, the demand for HPC and UHPC binders for military applications has been
increasing extremely for us. As reported earlier, we have produced and delivered several hundred tonnes of special HPC and UHPC for testing purposes. For these test purposes, special mixes were developed and produced according to customer requirements. The material pre-tests were carried out here in Germany. The military load tests are carried out in the respective customer country.

It is one thing to produce special UHPC combat concrete in peacetime under controlled conditions, it is another to produce such concrete under wartime conditions.
For this reason, we have also started a production and mixer system development in parallel to the binder development.
The technical requirements for such a system are very long and very complex.

Here is just a small excerpt from a list of requirements.

Requirement plant (40 feet container system)
- The system must be easily transportable
- The system must be robust

- The system must have an independent energy system.
- The system must be easy to operate
- The unit must be able to operate under extreme cold, heat and humidity conditions.
- The system should be divided into combinable modules.
- The plant should be able to produce binders and concrete
- The plant should have all the necessary processing machines
 

Requirement UHPC combat binder and combat binder concentrate
- The UHPC combat binder should be able to meet certain minimum technical values
- The UHPC combat binder should be produced as completely as possible with local raw materials.

- The concrete should be produced with local aggregates
- It should be possible to produce combat binder versions as mortar, castable, pumpable and sprayable.
- No additional additives should be necessary
- Extremely little mixing water should be used.
- The concrete should also be processable under extreme environmental conditions.
- The concrete should be workable under water
- It should be possible to use a wide variety of aggregates from destroyed buildings, sands, soils, plastics, metals, etc. The reprocessing should be as low as possible

The HPC and UHPC combat binder production and concrete mixing plant will soon be available to us as a basic prototype plant for testing purposes. Individual parts have already been in use for several decades. Several more special expansion stages will be available to our customers.
