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

Document Type : Original Article

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. RSA 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
workability 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.
