Abstract
Abstract: Geopolymer concrete has had an extra edge over normal concrete for the past 2-3 decades. According to research, geopolymer concrete offers improved strength, modulus of elasticity, and durability. In this work, Ordinary Portland cement is fully replaced by a mixture of Sugar Cane Bagasse Ash(SCBA) and Ground Granulated Blast Furnace Slag(GGBS), with alkaline liquids added for reactivity. Sodium Hydroxide (NaOH) and Sodium Silicate (Na2SiO3) are used for the polymerization to achieve good workability in the geopolymer concrete. The combined quantities of geopolymer concrete were optimized using the Taguchi method to meet the specified strength parameters for the concrete grade of M30 with nine mixes. Binder content, which included three proportions of SCBA and GGBS, NaOH/Na2SiO3 ratios (1:2, 1:2.5, and 1:3), molarity(4M,8M,12M), and alkaline activator to binder content ratio(AAC/BC) of 0.4,0.5,0.6 were among the various parameters of study. Compressive strength and split-tensile strength was investigated using these components and variables during the work.
