Abstract
Recently, there has been huge interest in the use of supplementary cementitious materials (SCMs) as a partial replacement for ordinary Portland cement (OPC) in concrete. This urge to replace OPC is due to the high carbon dioxide emitted into the environment during its production. Rice husk ash (RHA) is one of the types of SCM that can be used to replace OPC in concrete, and it is the waste product of rice production. This paper presents a detailed and recent review of the mechanical properties reported by various studies. It was concluded that with the right proportion of RHA incorporated into concrete, enhanced mechanical properties can be achieved. In addition, the use of RHA in concrete reduces the overall embodied carbon of the concrete, while reducing cost and utilizing waste generated by the agricultural industry.
