English abstract
Natural materials often posses excellent mechanical properties the cause of which is their microstructure based on the fibre reinforced matrix different in composition. For the design of the ultrahigh strength composites, the fibres based on the mineral or organic material and different in geometry are commercially available. The use of the proper microaggregate enables the preparation of the concrete based on the reactive powders (RPC), possessing unusually high compressive strength. The mixtures containing the special cement or portland cement, bauxite or basalt aggregate were tested. The randomly dispersed reinforcement based on the steel or polypropylene fibres were used. The water/cement ratio was between 0,16 0,25. The composites prepared reach the 28 day compressive strengths over 250 MPa.
