Study on Salf Compacting Using Admisture

Abstract

Self-compacting concrete using admixture is a specific type of concrete that can flow only by its own weight and can fill any space while keeping its homogeneity. This work summarizes the experiments for evaluating the performance of self-compacting concrete including slump flow tests as well as the recent achievements of the fresh and hardened properties of self compacting concrete such as slump flow, segregation resistance, compressive strength and tensile strength. Also, the previous researches of durability is surveyed including sulfate resistance, inner frost resistance, freezing and thawing. The effect of dosage amount of water binder ratio, water cement ratio and super plasticizer on the properties of self- compacting concrete are revealed based on the survey of previous literatures. Particular emphasis is placed on the availability and economic effectiveness of partial replacement of certain amount of cement by mineral admixtures, ordinary Portland cement.
