Abstract

Self-compacting concrete (SCC) is a highly flowable concrete which is able to fill the formwork and the areas of congested reinforcement completely under its own weight and without the need for vibration . Here Portland cement(PC) is replaced with 30%, 40% and 50% of SF, GGBS, FA. The w/p ratio is kept constant throughout the investigation as 0.35 .Superplasticizer known as Glenium B233 is used . The mix proportion is obtained as per the guidelines given by European Federation of producers and contractors of special products for structure(EFNARC). This paper presents an experimental investigation on strength aspects like compressive , flexural and split tensile strength and the workability tests (slump, L-box, Ubox and T50). The result of fresh property test satisfies the limits specified by EFNARC. It is observed that when the cement is replaced with mineral admixture,. decrease the overall CO2 production ,thus producing eco-friendly concrete .
