Self-compacting Concrete: A Review

Abstract

Compaction of concrete is often seen as a difficulty in traditional concrete, because poor compaction affects the concrete’s physical appearance, its strength and durability. It must be reduced by the use of SCC, a form of concrete that needs no mechanical vibration after placing as it flows into formwork on its own weight. The primary objective of the present study is to make use of hybrid fibres in the self-compacting concrete and understand its effects on the fresh properties, and other mechanical properties. The study also intended to quantify the amount of superplasticizers and fibre content to be added to the concrete according to the value of concrete properties measured. The basic properties of concrete materials are tested. The fresh tests such as slump flow test, V-funnel test and L-box test are conducted. The results showed that the workability of the self-compacting concrete decreased as the fibre content increases up to some percentages.
