Effect of Rice Husk Ash on the Properties of Concrete

Abstract

Abstract: As a binder for infrastructure development, conventional Portland cement is currently the primary material that is used. However, cement production has a substantial impact on the environment, and many pozzolanic materials can reduce their carbon footprint with conventional Portland cement. In this experimental study, replacement of OPC (ordinary portland cement) is replaced with the ash produced from rice husk (An agricultural waste) and analyzed for durability and strength performance in concrete samples and mortar as well as chemical composition analysis and microstructure observation of rice hull ash according to X-ray differential test data were also conducted in the research analysis. it is produced by burning of husk (produced by rice barley waste) of oxygen for the production of rice husk ash. Its chemical composition is rich in silicates and aluminates which promotes the binding property of ordinary Portland cement and does not affect the IST(Initial setting time), FST(Final setting time) and does not increase the fineness of the cement particles hence it gives significant results with cement replacement. It was determined that 10% rice husk ash replacement was the optimum value for rice husk ash replacement based on the strength and workability criteria of the concrete quality assurance system.
