Investigations on the Behavior of Alum-slag and Albite Based Geopolymer Mortar in Relation to the Type of Alkaline Solution

Abstract

An experimental investigation on the efficient use of Albite and red mud (aluminum slag) in geopolymer mortar is presented in this publication. For varying mix proportions, alka-line activators based on sodium were combined with sodium meta silicate (Na₂SiO₃). The Na₂SiO₃/NaOH ratio and the molarity of the NaOH solution served as the study's parame-ters. Three concentrations of NaOH (8, 12, and 16 molars) were examined. The findings demonstrated that the factors under investigation had a major impact on the characteris-tics of the geopolymer mortars that were created. The accelerated mortar bar test (AMBT), workability, setting time, and pozzolanic activity were examined and reported.
