Abstract
The concentration of sodium hydroxide solution increased the reaction rate during the geopolymerization process and thus enhanced the development of the early strength of concrete. The percentage volume of aggregates played a vital role in the strength development due to the better durability than paste alone and also filling and packing ability. The present study aims to determine the optimum molarity of sodium hydroxide and the aggregate ratio of geopolymer concrete towards high-strength performance concrete based on compressive strength and split tensile strength by conducting destructive and non-destructive tests. The variable samples investigated include the sodium hydroxide (NaOH) concentration and aggregate ratio to ambient temperature curing; the ratio of alkali activator solution and solid-to-liquid ratio remained constant. This is the result of the present work on the development of GGBS based geopolymer concrete having increment in the rate of strength development.
