Feasibility of Fly Ash for Manufacturing of Self Compacting Concrete

Self-compacting concrete is able to flow and consolidate under its own weight and is deaerated almost completely while flowing in the formwork. It is cohesive enough to fill the formwork of any size and shape without segregation or bleeding. SCC is found useful for heavily-reinforced concrete members or in complicated work forms. The objective of this work is to study the different test adopted on self-compacting concrete-like slump flow test, U-tube, L box, J ring and compare the same with conventional concrete. And also to compare the Compressive Strength values of self-compacting and normal concrete specimens at different ages and to study the effect of superplasticizer, VMA and fly ash on concrete. All SCC mixtures exhibited greater values in compressive strength after being tested, compared to normal concrete. The compressive strength of SCC is found to be higher than that of normal concrete. Use of mineral and chemical admixtures, which usually improve the bonding between aggregate and cement paste, thus increasing the strength of concrete.
