Abstract |
|
This paper investigates the optimum level of Rice Husk Ash (RHA) addition as a partial replacement of cement on the compressive strength, flexural and split tensile strength of concrete. Referral concrete of M40 with cement content 460kg/m^3 was used for the study. Test concrete are obtained by replacing 0%,10%,20%,30%,40% of cement content with RHA. Specimens for compressive strength were cured in water for 7, 28, 56 and 90 days after the demoulding of 24 hours and other specimens for 28 days only. It is evident from this study that the mechanical properties of concrete containing RHA increases with its RHA content increment till an optimum replacement level at 20%. Further addition to this level shows a decreasing trend. |
