Abstract

Cement is the cheapest constituent of concrete. Over 5% of worldwide CO2 production is official by cement production. Similarly, due to the order in the fine aggregate. In this work, every second source for fine aggregate as rice husk ash is used. A study on properties of concrete when fine aggregate is in some measurer placed by rice husk ash. Percentage replacement of Fine aggregate with Rice Husk Ash (RHA) is fine aggregate is replaced at 0%,5%,10% and 15% in a mix of M25 grade of concrete. The strength such as compressive strength is found out at 7, 14 and 28 days. The strength is comparing with concrete and the most favourable % of replacement of RHA is found out.

Key-Words / Index Term
