Current knowledge about the properties, technology and structure of high strength concrete is presented. Significant parameters needed in the analysis of load-bearing, ductile and acceptable reinforced-concrete elements made of such concrete and subjected to bending, with longitudinal force or without this force, are considered. These parameters are: design compressive stress diagram, ductility, ... [Show full abstract] deflection, and crack width restraint. The results are compared with values for normal strength concrete. The use of high strength concrete is recommended.
