The composite binder for self-compacting concrete

Abstract

Application of self-compacting concrete (SCC) is one of the prior directions in modern construction. Despite the reduction of energy consumption in the production of reinforced concrete structures, high physical and mechanical properties, the SCC is more expensive material compared to conventional vibration compaction concrete. One of the solutions of this problem is the use of secondary products industry as raw material components of the SCC. The effect of water treatment of sludge of thermal Electrical Station on the kinetics of a set of strength of the cement stone, together with the introduction of its hyperplasticizer was studied. The possibility of using water treatment of sludge as dispersed filler was shown, the optimum filler content and hyperplasticizer was defined.
