A Comparative Study of Strength Properties of Self Compacting Concrete over Conventional Concrete

Conventional concrete tends to present a problem with regard to adequate consolidation in thin sections or areas of congested reinforcement, which leads to a large volume of entrapped air voids and compromises the strength and durability of the concrete. We can eliminate the problem by using self-compacting concrete (SCC), since it was designed to unite under its own mass. Normal concrete was designed as IS method and self-compacting concrete was designed by a simple mix design proposed by Nan Su. SCC was developed in 1988's by Prof. Hagime Okaura in Japan. SCC was one of the latest concrete in across the world. This project deals with the comparison of two different type of high strength concretes. Which is high strength of normal concrete and self-compacting concrete. An experimental and numerical study on mechanical properties, such as compressive strength, flexural strength and split tensile strength of self-compacting concrete (SCC) and the corresponding properties of normal compacting concrete (NC) were studied. The age at loading of the concretes varied between 7 and 28 days.
