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.
