In 2008, Dyckerhoff won the Innovation Prize for Structural Concrete Products of the Supplier Industry for Dyckerhoff Nanodur. In order to enable the production of UHPC in conventional concrete mixing plants, Dyckerhoff further developed these binders to become Nanodur Compound 5941. However, for the production of 1 m³ of concrete more than 1,000 kg of the binder had to be transported over very long distances to the job site so far.
Therefore, with Nanodur Extract, Dyckerhoff has now developed a concentrate which is added to the binders and limestone powder being already available at the job site. Only approx. 230 kg of the concentrate are needed for the production of 1 m³ of UHPC. Usually, the cements and silica sands available from the local market are used accordingly, with reducing the transport costs and increasing above all the sustainability.
Because of its dimensional stability, durability and strength, UHPC provides the prerequisites for a material-saving, slender and thus sustainable construction design, yet offering the same load-bearing capacity.
Currently, the German Committee for Reinforced Concrete (DAfStB) is finalizing a guideline on „Ultra-High Performance Concrete“ and has announced its publication for 2020. After the entry into force, Dyckerhoff expects a boom in construction with UHPC. In comparison with ready-made building materials, Nanodur Extract considerably contributes to minimizing transports of building materials and thus to a reduction of the CO2 emissions, too.
