High-performance concretes

High-performance concrete as a challenge

Ultra-high performance concretes (UHPCs) are building materials with an extremely dense matrix whose properties are very similar to those of steel. Factors that currently prevent a more common use of this high-performance construction material include its high cost and technical approval to be granted in each specific case, and, particularly, the complex production process. The OLAF project (“Nanotechnisch Optimierter Langlebiger, energieeffizienter und insbesondere AnwendungsFreundlicher Hochleistungsbeton”, i.e. durable, energy-efficient and, in...
