Abstract
The results indicate the development of geopolymer concrete using GGBS and RHA with high 3-day compressive strength of approximately 60â¯MPa, which can replace the conventional cement concrete and thus reduce carbon dioxide emissions. Also, the increase in compressive and split tensile strength, and reduction in chloride permeability and sorptivity was observed with the inclusion of RHA up to 15% at all ages. Beyond this optimum content of 15%, RHA inclusion showed negative results. In addition, the results of microstructure analysis showed more compact and dense micrograph of geopolymer concrete with 15% RHA, due to the coexistence of polymerization products with the additional calcium based hydration products.
