Objective: Durability one of the critical role effect in geopolymer serviceability. The capability of water to penetrate the mortar microstructure is mainly used to measure the durability, which also called permeability. Methods/Statistical Analysis: The influence of sodium hydroxide (NaOH) molarity, alkali Solution to Binder ratio (S:B), binder to aggregate ratio (B:A) and sodium silicate to sodium hydroxide ratio (NS:NH) on water absorption of Geopolymer Mortar (GPMs) are investigated in this article. Geopolymer mortar specimens of different NaOH molarity, S:B, B:A, and NS:NH were prepared and cured at different temperatures, 27°C and 60°C. Granulated blast furnace slag, fly ash, waste ceramic and waste glass bottle were used as a binder and mixed with river sand as fine aggregate. Findings: The results of experimental indicated that water absorption significantly affected of curing temperatures. The lower water absorption results were observed of the samples cured at ambient temperature (27°C) compared to samples cured at oven temperature (60°C). Applications/Improvements: The geopolymer specimens’ water absorption observed positively enhanced with increase concentration of alkaline solution.
Keywords: Geopolymer, Sodium Hydroxide Molarity, Water Absorption.
