“…Carbon dioxide emissions from the cement manufacturing sector are predicted to account for about 7% of worldwide CO 2 emissions, and total carbon emissions from the world's cement industry are expected to grow by4% by 2050 [1] [6]. To mitigate global warming and overall cost of concrete production, many researchers have intensively researched the utilization of waste materials from industries and agriculture such as waste paper sludge ash [7] [8], electric arc furnace dust [9] [10], waste foundry sand [11] and rice husk ash [12] [13], corn cob ash [14], rice straw ash [15], coal bottom ash [16] and sugarcane bagasse ash [17] as partial cement replacement in concrete and mortar.…”

Increasing the population and infrastructure in both emerging and developed countries requires a considerable amount of cement, which significantly affects the environment. The primary materials of concrete ('cement') production emit a large quantity of CO 2 into the environment. Also, the cost of conventional building materials like cement gives motivation to find geopolymer waste materials for concrete. To reduce harmful effects on the environment and cost of traditional concrete substance, alternative waste materials like rice husk ash (RHA), ground granulated blast-furnace (GGBS), fly ash (FA), and metakaolin (MK) can be used due to their pozzolanic behavior. RHA waste material with a high silica concentration obtained from burning rice husks can possibly be used as a supplementary cementitious material (SCM) in the manufacturing of concrete, and its strong pozzolanic properties can contribute to the strength and impermeability of concrete. This review paper highlights a summary of the positive effect of using RHA as a partial substitute for cement in building construction, as well as its optimal inclusion of enhanced mechanical properties like compressive strength, flexural strength, and split tensile strength of mortar and concrete.
