Abstract:
Concrete samples of standard mix of 1:2:4:0.55 with water of different pH values ranging from I to 12 were cured in a water tank containing distilled water for 7, 14 and 28 days at room temperature after which they were tested for compressive strength. Results showed that the compressive strength of concrete decreased as the value of the hydrogen ion concentration increased and as the basicity of the mix water was increased, the strength of concrete was reduced. The highest compressive strength of 33.5 kN/mm2 was achieved at a mix water pH of 7.
