High Performance Concrete Experimental Structure

Abstract

An experimental structure from high performance concrete was created within the scope of long-term research and development program of the Department of Concrete and Masonry Structures, Faculty of Civil Engineering, CTU in Prague that is focused on advanced cementitious composites. The intention was to build a structure of so called “CyclePoint” (resting place for bikers) interesting from architectural point of view and made from non-traditional, high durability material. Transfer of high performance concrete composition designed in the laboratory to the mixing plant construction company was accomplished. This required series of confirmation material tests. The technology of casting high performance concrete into the formwork of thin-walled precast elements was optimized. The use of engineered mix of fibres enabled the authors to design structures without main rebar reinforcement. The design was carried out using finite element based software and verified by loading experiments executed on structural elements in full-scale.
