In the present experimental investigation, acid resistance tests were conducted as part of durability studies on geopolymer concrete (GPC) composites. Mineral admixtures like ground granulated blast furnace slag (GGBS), condensed silica fume (CSF) and metakaolin (M.K) were employed as replacements to fly ash at various percentages in the GPC mixes. After subjecting the samples to 28 days of ambient curing, they were exposed to 5% solutions of hydrochloric acid (HCl) and sulphuric acid (H2So4) over various periods ranging from 0 to 60 days. After exposure, the change in weight and the compressive strength of samples were determined. Improved performance of GPC mixes was noticed in acid resistance and compressive strength when the mineral admixtures like GGBS, CSF and MK were used as replacements to fly ash.
