Abstract: | In this report, the detailed experimental investigation was done to study the effect of partial replacement of cement by Rice Husk Ash (RHA) and silica fume (SF) in various proportions starting from 15% RHA to 30% RHA and 5% SF to 10% SF. The tests on hardened concrete were destructive in nature which includes compressive strength test on cube of size (150 x 150 x 150 mm) at 7,28,56 and 90 days of curing as per IS: 516 1959, Flexural strength tests on beams of size (100 x 100 x 500 mm) at 7,28,56,90 days of curing as per IS:516 1959 , compressive strength test on cylinders of size (150 mm ø x 300mm height ) at 7,28,56,90 days of curing as per IS: 516 1959 and Drop weight impact test on disc of sizes (150 mm ø x 60mm) as per ACI 544. The work presented in this report reveals the effects on the behaviour of concrete produced from cement with combination of SF and RHA at different proportions on the mechanical properties of concrete such as compressive strength, flexural strength, and impact strength. From this study it is found that 25% replacement of RHA and 7.5% replacement of cement with SF are the optimum level of replacement. |
