Strong Acidic substances like HCl (Hydrochloric acid) and H2SO4 (Sulphuric acid)are abundantly present in tropical and subtropical surface water bodies. Strong acids (HCl and H2SO4) and water have an important role in the properties of concrete. The current study aims to investigate the effect of strong acidic substances like HCl and H2SO4 with various concentrations mixed in water on setting time, soundness, and compressive strength of admixture cement. Admixture cement is used and cubes were cast with deionized water containing with and without strong acids. The results show that the strong acids in deionized water effects the initial and final setting times in all the concentrations. Strong acids in deionized water decrease the compressive strength from an early age (3-days) to the maximum age (2 years). The hydration characteristics of the admixture cement with deionized water containing and without strong acids have been studied
