Influence of Albite Activator in Geopolymerisation of Slag Wastes from Iron and Aluminium Industry

Abstract

Geopolymerization mechanism involves the reaction between materials rich in silica and alumina in the presence of alkaline medium to form a polymer structure. Present study involves in usage of the raw materials, which are the waste slag products from iron industry (GGBS) and aluminum industry (RED MUD – RM) in the various proportions of RM: GGBS as 0:100,25:75,50:50,75: 25,100:0 in presence of albite activator(AA) and NaOH which initiates polymerization and finally resulted in obtaining geopolymer concrete(GPC). Various experiments were conducted to analyze the mechanical and microstructure performance of the obtained GPC and therefore compared with the normal conventional concrete. Results showed that with 0% RM and 100% GGBS performs best when compared to Normal conventional concrete(NCC).
