Mechanical properties of a geopolymer concrete/ultrafine material based composite

Industrial development leads to numerous slags; therefore, by-products from the industries should be effectively handled.In this novel work, fly ash and crushed-stone sand along with ultrafine ground granulated blast-furnace slag (UFGGBFS) were mixed to study the performance of 10M, 12M and 14M geopolymer concrete.As per Indian standards, the properties of UFGGBFS-incorporated geopolymer concrete (GPC) were examined by testing the flexural strength, compressive strength, water absorption and splitting tensile strength.The values infer that an addition of UFGGBFS and fly ash to GPC stimulates these properties so that the material can be an alternative to conventional concrete.UFGGBFS-based geopolymer concrete improves the densification and interfacial transition zone.An increase in the molarity resulted in a strength gain of all the prepared specimens.
