This book reports the study of compressive strength and split tensile strength of concrete involving rice husk ash (RHA) and plastic fiber in different proportions. M-20 grade of concrete was taken for experimental study. RHA content was used from 5% to 15% at the interval of 5% by replacing Ordinary Portland Cement (O.P.C.) and plastic fibers were used from 1% to 3% at the interval of 1% by replacing the coarse aggregate. Plastic fibers were obtained by cutting the polythene bags into small pieces. The compressive strength and split tensile strength of concrete was checked at 7 days and 28 days of curing period. The results show that concrete samples having RHA and plastic fibers showed better strength as compared to controlled concrete samples.
