INFLUENCE OF GGBS & SILICA FUMES ON STRENGTH OF SELF-COMPACTING CONCRETE (SCC)

High seismicity in geographical region requires the use of high level steel reinforcement in construction. The use of SCC appeared as a solution to improve the filling up of zones which are not very accessible to conventional method of concrete compaction. But use of the Self-compacting concrete is uneconomical. We can try to make it economical by replacing cement with other by products. In this research, we have replaced cement with GGBS and Silica fume. By conducting trail mixes with those products we came to know that the strength increases for the mix of 20% GGBS and 4.23 % of Silica fume and after that it get decreases.
