Abstract
Abstract: It is important to durable of structure and reduce co2 emission through the greater use of substitute of cement. The use of supplementry cementitious materials as partial replacement for the cement in concrete will play a significant role with respect to the environmental control of greenhouse and global temperature reduction. The development of geopolymer concrete (GPC) processing of geopolymer using black rice husk ash, GGBS in combination with sodium hydroxide and sodium silicate solutions, offers a promising alternative to ordinary portland cement concrete. This study compares the different ratio of black rice husk ash to GGBS where50:50 60:40 40:60 ratios and differing the molarities of alkaline solutions which are 8m , 10m and 12m and comparing the strength of the above ratios and conducting durability characteristics of fly ash and GGBS based geopolymer concrete by conducting test procedure like compressive strength , split tensile strength test, sorpitivity test. Keywords: Geo-polymer concrete ,Black rice husk ash (BRHA),Ground granulated blast furnace slag (GGBS).
