Part 22: High strength concrete, high performance concrete

Abstract

UHPC (Ultra High Performance Concrete) is a high tech material with outstanding properties.Because of its need for special regard at production and casting an application in the precast industry is generally recommended. Furthermore, the costs of UHPC are nearly 10 times higher compared to ordinary concrete. For economic use of this high tech material, new design philosophies in concrete construction have to be developed. Suitable construction types and building methods are filigree, flexible and modular constructions with precast elements. This effectively combines the high-performance material properties and the special features of this new material with the demands for sustainability, fast construction progress and wide application. This contribution presents general considerations on modular UHPC constructions by introducing three recent examples of UHPC application. Finally this illustrates the high potential of UHPC for sophisticated constructions in both aspects, architecture and structural engineering.
