Abstract: Concrete is an essential building material is widely used in the construction of infrastructure such as buildings, bridges, highways, dams, and many other facilities. Cement the second most consumed product after the water in the world. Geopolymer concrete (GPC) is manufactured using industrial waste having Silica and alumina like fly ash, Red mud, RHA paper ash etc. which is consider as more economical and eco-friendly alternative to OPC based Concrete.
The feasibility of production of GPC using Rice Husk Ash (RHA) is evaluated in this study. Additionally the initial and final setting time of Geopolymer paste based on RHA is also studied. For this Study the molarity of NAOH is kept constant that is M16and the alkaline solution ratio is 1:1.85 and alkaline solution to source material is 0.7 & 0.8. Study Show that Geopolymer concrete based on RHA gives good compressive and flexural strength as compare to Ordinary Portland Cement Concrete at different mix.
Keywords: Geopolymer concrete (GPC), Rice Husk Ash (RHA), buildings, bridges, highways.
