Abstract

An increasing need for sustainable construction materials caused the invention of geopolymer concrete, a green substitute for traditional Portland cement concrete. The present research examines the role of alcofine in improving the mechanical characteristics of geopolymer concrete incorporating rice husk ash (RHA) as a derivative. Alccofine, a high-performance supplementary cementitious material, was added in varying proportions to the geopolymer mix containing RHA and Ground Granulated Blast Furnace Slag (GGBS). Experimental findings demonstrated significant improvements in the flexural strength, compressive strength, and tensile strength of geopolymer concrete with the inclusion of Alccofine. The synergistic effect of Alccofine and RHA not only improves the structural performance but also addresses environmental concerns by utilizing industrial by-products. This study underscores the potential of alcofine in producing high-performance geopolymer concrete suitable for sustainable construction applications.
