Experimental Investigation on Compressive Strength of Concrete with Partial Replacement of Cement with Silica Fume

Abstract

The purpose of this experimental investigation is to study the behavior of short columns produced from Silica fume concrete (SFC). In this investigation SFC was manufactured by usual ingredients such as cement, fine aggregate, coarse aggregate, water and mineral admixtures such as Silica Fume (SF) at various replacement levels. When coarse aggregate and fine aggregate

ratio (ca/fa ratio) of the mix is varied and various percentage replacement of cement with silica fumes in the concrete. The percentage of silica fume varied are 0%, 11%,13%,15%, and 17% as equal replacement of ordinary Portland cement. The water binder ratio (w/b) adopted is 0.42 and 0.50. The ca/fa ratios range from1.50 to 1.75. After demoulding, the concrete specimens from each mix will be moist cured in water for 28 days. The compressive and tensile strength will be determined after each curing period.
