Abstract

Cement production is energy-intensive resulting in the emission of carbon dioxide (CO<subscript>2</subscript>) which is responsible for global warming. Rapid surge in the global energy demands needs to pave way for the need for a viable and sustainable alternative to concrete, which not only reduces our dependence on natural resources but also can be a possible alternative to the concrete industry and geopolymer technology can be one such material. Geopolymer technology can use secondary raw materials from the agricultural and industrial waste with alumina-silicate phase in presence of alkali activator for the production of geopolymer concrete. This paper comprehensively summarizes the previous research; along with analysis is carried out to propose descriptive equations to establish the correlation between the mechanical strengths (Compressive strength with Split tensile strength, Flexural strength and Modulus of Elasticity) of geopolymer. Current findings suggest substantial practicality and a possible alternative to cement in the construction industry [ABSTRACT FROM AUTHOR]
