Abstract

This paper presents the performance of concrete partially cement replaced with rice husk (RA) and bagasse ashes (BA) both in fresh and hardened state. The study the parameters included workability, compressive strength, and flexural strength of the concrete. The variables considered were of types of ash and its percentage replacement (0%, 10%, 20% 30% and 40%) by weight of cement content. Four different types of concrete specimens such as: concrete without replacement as reference, concrete replaced with RA, concrete replaced with BA, and concrete replaced with combination of RA and BA were cast. All the fresh and hardened properties of the concrete were obtained in accordance with Bureau of Indian Standards (BIS). The experimental results show that the workability of the concrete decreased with increase in percentage replacement. The strength properties of the combined RA and BA concrete were found to be increased up to 20% replacement because of different pozzolanic reactions when compared to the other specimens.
