Effect of chemical (Sodium Hydroxide, Sodium Silicate, Borax) dosage on Setting Time and Compressive Strength of GGBS mortar

Abstract

Initial setting time and final setting time of GGBS are evaluated varying the chemical parameters. The chemicals used are sodium hydroxide, sodium silicate and borax. In the first trial the molarity of NaOH is kept constant and the borax content is varied and graphs are plotted for the results to be tabulated. The setting time is dependent on the molarity and the borax content. The test for compressive strength of GGBS mortar is also done for varying both molarity and borax content for 7 and 28 days. It is observed that the compressive strength is also dependent on the molarity and borax content. More the molarity and borax content more is the compressive strength.
