Abstract

Three alkali-activated mortars (AAM), or what is called geopolymer, mix with different fly ashes sources were tested during the study. X-ray fluorescence was carried out on AAM samples to determine their chemical composition. Flowability and setting times of the AAMs were tested. Compressive strength was analyzed for five different temperatures of 30, 40, 55, 70, and 85 °C under five different time intervals of 4, 8, 16, 24, and 48 h. The compressive strength results indicate that the calcium content and ratio of silica to alumina played a pivotal role in the optimum curing conditions for each of AAMs.
