Self-compacting geopolymer concrete using Class F Fly Ash

Abstract

The development of self-compacting geopolymer concrete has the dual advantages of reducing environmental pollution and managing waste. The objective of the current experimental study is to create self-compacting geopolymer concrete with the best sodium silicate to sodium hydroxide ratio utilizing class F fly ash and sodium hydroxide. With varying sodium silicate to sodium hydroxide ratios (2.1, 2.3, 2.5, and 2.7), different molarities of sodium hydroxide (NaOH) (10M, 12M, and 14M) have been examined for workability and strength behavior. Self-compacting geopolymer concrete is found to be the ideal combination for a 12M sodium hydroxide solution and a 2.5 ratio of sodium silicate to sodium hydroxide solution.
