Abstract

Self compacting concrete is a highly workable concrete that can flow through densely reinforced complex structural elements under its own weight and adequately fill all voids without vibration or mechanical consolidation. Effective use of industrial waste products in concrete gains many economic, environmental and social benefits rather than disposing of it as waste. The objective of this study is to find out the optimum replacement of blast furnace slag as a partial replacement for coarse aggregate in M20, M30 and M40 grades of fly ash blended self compacting concrete. The coarse aggregate was replaced from 0 to 100 % with an increment of 10 % by blast furnace slag aggregate and the various self compactability and strength properties were determined and compared. From the results, it is found that 32 % of slag aggregate can be replaced for coarse aggregate to attain both self compactability and strength for concrete applications.
