Abstract

Pollution is the most important aspect on which we have to think about. Cement being the most important material in the concrete causes the environmental pollution in its production. To overcome this problem use of various by-products should be done. In the present study the Ground Granulated Blast Furnace Slag (GGBFS) & Rice Husk Ash (RHA) materials are used in the replacement of Portland cement and alkaline liquids are used for the binding of materials. Many researchers have been carried out for determination of percentage combination of GGBFS and RHA. In this study, combination of GGBFS and RHA is taken as 90% GGBFS and 10% RHA [1] and effect of Sodium Hydroxide Molarity & ratio of Na2SiO3/NaOH are checked. The alkaline liquid is the mixture of Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3). Various Na2SiO3/NaOH ratios are taken as 2 and 3. Various molarities of Sodium Hydroxide (NaOH) are taken as 10M, 12M, and 14M. The cube specimens and cylindrical specimens will be casted and Compressive strength test and split tensile strength test are conducted. Test results show that geo-polymer concrete with 12M NaOH and ratio of 3 Na2SiO3/NaOH produced maximum compressive strength. As per results Geo-polymer concrete can be developed at ambient temperature using GGBFS and RHA.
