ESEARCH OF THE PROPERTIES OF THE SELF-COMPACTED CONCRETE OVER TIME

Abstract

Concrete mixture is examined as a complex multicomponent system that becomes a single unit and can be studied as a physical unity with certain rheological, physical and mechanical properties. Studying the change of properties of self-compacted concrete over time, as well as the effect of two-phasic introduction of super-plasticizer on properties of concrete mixture are presented in this article.
