Abstract Geopolymer is one of the trending research areas in composite materials; there are many areas in geopolymer that unexplored still need to be explored. In this paper, an attempt is made to explore such an area and develop high-performance concrete. The optimal percentage of slag and activators, such as potassium and calcium hydroxide ratio, were investigated in metakaolin-based geopolymer. At ambient conditions, alkaline to binder (A/B) ratios of 0.25, 0.35, and 0.45 were used to cast the different proportions of geopolymer concrete at ambient conditions when tested at 7, 28, and 90 days. The fresh, mechanical properties, probability, matrix andsmoothening plot for modulus of elasticity of geopolymer were investigated. Ishikawa diagram,which signifies cause-and-effect factors of geopolymer concrete is discussed. Geopolymer was observed to have medium workability and mechanical properties and showed excellent results compared with traditional concrete at 30 % slag usage at a 0.35 ratio of A/B. At 30 % of GGBS, geopolymer concrete optimum mix maximum strength was observed.trix Matrix, and smoothening analysis show that linear relationships vary among the parameters used for analyses.
