Abstract

Self-compacting concretes (SCC), a new type of concrete, were realized with the development of polycarboxylate-based chemical additives. The interaction of these additives with the powder materials in the nano and micro scales affects the fresh and hardened properties of concrete in meso and macro scales. To change and improve the macro-dimensional properties of concrete, it is necessary to better analyze the nano-micro-dimensional interaction. The aim of this study is to examine the interactions of cement, mineral and chemical additives in micro scale. For this purpose, the zeta potential values of the mixtures consisting of cement, water, calcite and blast furnace slag prepared by using a polycarboxylate based plasticizer additive were analyzed. In addition, SEM analyzes of hardened samples were made on the 28th days.
