Self-compacting concrete with finely dispersed additives and superplasticizer

Abstract

This article investigates the features, qualitative characteristics, and structure of self-compacting concrete (SCC). In particular in this article we present the results of research into the influence of finely dispersed fillers with superplasticizer on physical and mechanical properties of self-compacting concrete. By developing the optimum compositions of different types of concrete, we determined the compressive strength of self-compacting concrete. We proved that plasticizing additive MasterGlenium ACE (Admixture Controlled Energy) significantly liquefies concrete mixture, which allows obtaining self-compacting concrete. The influence of finely dispersed fillers and plasticizers on the density of the concrete mixture was also studied. During the research the effectiveness of the complex application of silica fume (SF) and plasticizer was identified. The results of the research confirm the effect of the amount of fine aggregate and the amount of ACE affecting the workability of the concrete mixture and its strength.
