Abstract

This research was studied to check the workability and strength properties of an pervious concrete along various percentage mix of rice hush ash with cement. The RHA was added partially to the cement to increase the strength of pervious concrete. In general RHA is an agricultural waste considering that 20% of the grain is husk and those 20% is combusted and made in RHA and it can be utilized in the partial mixing with cement. RHA has contain silica. Silica is a good chemical admixture to increase the strength of concrete. By using this RHA we can reduce the environmental impact and also eco friendly and free of cost. since india is the largest producer of rice we can obtain in plenty. In this study components used for pervious concrete is opc M53 grade cement RHA, 12.5mm and 20mm coarse aggregate & water. Since pervious concrete don’t have proper mix ratio so we have obtained mix ratio by trial and error method. So we considered different mix proportion such as 1:1, 1:2, 1:3, 1:4, 1:5, 1:6, 1:7& 1:8 among this mix we have got better strength in 1:4 mix ratio of cement and coarse aggregate and 0.3 water cement ratio. in this study we are going to compare the strength of pervious concrete by different mix % of 20%, 25%, 30% of RHA with various size of 12.5mm & 20mm coarse aggregate.the pervious concrete was casted in cubes of 150 x 150 x 150mm moulds and beam of 170 x 150 x 150mm to find compressive and flexural strength of concrete. When the RHA content is increased beyond 30% the compressive & flexural strength of concrete reduced comparing to the conventional pervious concrete.
