Effect of Rice Straw Ash on the Behaviour of High Performance Concrete Mixes

Abstract

This research aims to investigate the effect of rice straw ash on the behaviour of high performance concrete mixes. Using Rice Straw Ash will eliminate the environment pollution and provide a low cost construction material. R SA will be used as an additive or as a replacement of a part of cement content. The effects of RSA on the properties of fresh and hardened concrete were investigated to produce high performance concrete. The study includes measuring the workab ility of concrete by slump and slump flow tests. Also, it includes the properties of the hardened concrete such as compressive, tensile, and flexural strength are measured.
