Abstract

The goal of the current study is to better understand the limitations on the durability of geopolymer concrete manufactured from Class F fly ash and GGBS, two industrial waste leftovers. OPC and GPC concretes are created using the M50 grade under ambient curing. The produced concretes were evaluated for strength and sorptivity and water absorption properities as well as for strength and durability against sulphate and chloride attack.During 28and 90 days, 1, 3, and 5% concentrated solutions of H2SO4, HCl, and NaCl were applied to GPC and OPC concrete, respectively. In this investigation, a 2.5 alkaline liquid to binder ratio was used. For this investigation, a molarity concentration of 10 of NaOH was used. Steel fibers are used at a dosage of 0-2% with an increments of 0.5% by weight of cement. Tests were done on characteristics such density, surface degradation, and compressive strength. To explore microstructural qualities, samples were also subjected to XRD analysis and SEM image characteristics. GPC concrete performs better than OPC concrete in terms of resistance to sulphate and chloride attack.The test findings showed that under aggressive media, GPC concrete over the designated time period attained better strength and durability qualities to OPC concrete.
