DEVELOPMENT OF SLAG BASED LOWER STRENGTH SELF COMPACTING CONCRETE AND EXPERIMENTAL ASSESSMENT ON ITS STRENGTH AND ELASTIC PROPERTIES

The main scope of this research paper is to achieve the optimum level of GGBS to develop the lower final strength and cost effective Self Compacting Concrete (SCC) . An extensive experimental study of mechanical properties and the elastic behaviour of slag based self compacting concrete is presented in this paper. To maintain the fresh concrete's rheological properties and, at the same time, achieve lower final strength, reduced amount of Portland cement needs to be proposed in the mixture design. In this current research, SCC was produced by blending GGBS with cement in three different ratios and 50% Crusher Rejected Fines is incorporated in all scc mixes as useful disposal of a waste product from quarry end and also which leads to economical benefits. Based on the experimental results, it was found that SCC mixture containing 50% GGBS replacement to cement and 50% CRF to river sand exhibited possibility of lower target strength of M25grade. The obtained experimental E value is applied to explore the possibility of structural application of the developed SCC mixes
