Towards local Large-Scale Production of UHPC in Norway

Abstract

Investigations are presented on development and testing of ultra-high-performance concrete (UHPC), suitable for large-scale production in standard industrial equipment for mixing and transportation of conventional ready-mix concrete (RMC) and based on locally produced constituents. Experiments were conducted both on a large-scale at an RMC plant and on a small-scale in the laboratory. The objective was to facilitate more widespread implementation of UHPC in construction projects. The findings indicate that UHPC can be produced and transported with the equipment of conventional RMC plants, using local materials and various ores of aggregate. The results demonstrated comparable results from laboratory and large-scale production, despite the use of different ores for aggregate. It is suggested that local production might support more widespread use of UHPC, also through increased building of competence.
