| Abstract | This paper deals with the effect of hydrochloric acid (Hel) and sulfLiric acid (H2S04) present in mixing water on properties of setting times, compressive strength and tensile strength of cement concrete. The results indicate that the initial and final setting times get retarded due to acidity imparted by Hel and H2S04. HydrochloriC acid when present in water retarded the initial and final setting times considerably when its content was exceeded by 500 mg/L and 300 mg/L respectively. Sulfuric acid retarded the initial and final setting times significantly when its content exceeds 300 mg/L in mixing water. The rate of development of compressive strength and tensile strength decreased with the increase in concentration of both Hel and H2S04 for 28days and 90 days. However this decrease is significant at concentration of 500 mg/L and 300 mg/L for Hel and H2S04 respectively. |
