Abstract
Abstract This paper presents the results of research of self-compacting concrete produced with recycled concrete aggregates and activated filler. The physical and mechanical characteristics of coarse aggregate, grain distribution of aggregates and sand proportion in aggregate mix, design of self-compacting concrete mixture and it’s structure properties with use mathematical experiment planning method were carried out. The results indicated that optimal content of filler is 22% with 150 min of activation and 0.5% content of organic admixture. Standard consistency of composite binder has decreased from 26.5% to 22.4%. The mathematical models can be used in the design of the self-compacting concrete mixture.
