Having a prediction model for the geopolymer concrete (GPC) compressive strength gives Engineers an edge in project quality and cost control. Compressive strength of geopolymer concrete is dependent on various components that formed the concrete, and the curing regime. This paper is the outcome of a review of various variables (components and relationships) that influence the compressive strength of (GPC). The variables identified from the literature are; Concentration (Molarity) of the Hydroxide solution, Alkaline Liquid/Geopolymer Solids (Liquid/Binder) ratio, Sodium silicate to Sodium hydroxide ratio (SS/SH), curing time, curing temperature, Water/Geopolymer Solids ratio, age, fineness of the binder (pozzolan), rest period, admixtures and aggregates. A careful examination of the influence of each variable on compressive strength revealed that Hydroxide concentration, SS/SH, curing temperature, Alkaline Liquid/Geopolymer Solid ratio and Water/Geopolymer Solid ratio are the major determinants of GPC compressive strength.
