Sewerage systems made of UHPC

For extreme conditions of use in practice –

The development of high-strength and ultra-high performance concretes (UHPC) has been discussed among experts and promoted for several years now. The short term UHPC refers to concrete grades with material properties being significantly higher than the standard values, for examples, of the German standard DIN EN 206-1. The concrete types made of UHPC offer a wide range of new and filigree construction possibilities providing a high load-bearing capacity and slender cross-sections. Apart from numerous theoretical surveys and the corresponding research projects, practical applications are...
