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</span><sub><span style=\"font-family:Verdana;\">2</span></sub><span style=\"font-family:Verdana;\"> 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.
