This paper reports the results of a study conducted to investigate the effect of casting temperature under constant curing conditions on the compressive strength of concrete specimen of size 150x150x150mm made from PPC cement. The concrete specimens were cast at 15 ℃,20 ℃,25 ℃,30 ℃,35 ℃,40 ℃, and 45℃ and cured by means of submerging them in curing tanks that were maintained at 30℃. Water-cement ratio adopted was 0.45. Compressive strength after 1day, 3day, 7day, 28 day and 56 day were evaluated and the results were plotted in graphical representation and in tabular form. The optimum casting temperature for the plain concretes was found by measuring compressive strength of concrete .The optimum casting temperature was noted to be 30℃ for PPC cement concrete specimens.

Compressive strength, Casting and curing temperature, aggregates, water- cement ratio, slump, heat of hydration, rate of gain and loss of strength, optimum temperature.
