Replacement of Cement with Rice Husk Ash in Concrete


Article Preview

In the present investigation, a feasibility study is made to use Rice Husk Ash as an admixture to an already replaced Cement with fly ash (Portland Pozzolana Cement) in Concrete, and an attempt has been made to investigate the strength parameters of concrete (Compressive and Flexural). For control concrete, Indian Standard (IS) method of mix design is adopted. Five different replacement levels namely 5%, 7.5%, 10%, 12.5% and 15% were chosen for the replacement study. A range of curing periods starting from 3 days, 7 days, 28 days and 56 days are considered in the present study. Series ranging from 5% to 10% RHA concrete but better compressive strengths at later ages though showing lower compressive strengths initially. However, split tensile strengths are lower for RHA concrete when compared to normal concrete.
