The present study is carried out for evaluating the influence of Rice-Husk Ash and COIR Fibers in M20 grade concrete. This paper presents the results of compression test and split tensile teston concrete which were casted with various percentage of COIR fibers ranging from 0% to 4% at a regular interval of 1% and Rice-Husk Ash ranging from 0% to 20% at regular
interval of 5%. Total 3 cubes and 3 cylinders were casted for each mix design, there were total 17 mix designs, averageresult of 3
cubes and 3 cylinders was taken as final compressive strength and tensile strength of that mix design. Out of 51 cubes and 51
cylinders,3 cubes and 3 cylinders were casted as control mix (M20 grade concrete without Rice-husk ash and COIR fibers), remaining 48 cubes and 48 cylinders were casted with different percentages of Rice-Husk Ash and COIR fibers. Results clearly
indicated that with increase in % of Rice-Husk Ash and COIR fibers the compressive strength and tensile strength of concrete
increases, it can be clearly seen that cement can be replaced up to 20% with Rice-Husk Ash and COIR fibers without compromising the compressive and tensile strength. As a result the concrete becomes economical and also impact on environment decreases due to agricultural waste, industrial waste and also due to emission of CO2 gas in environment while manufacturing of cement.
