Abstract:
The effect of temperature on strength of Portland cements was investigated in series of tests made on concretes cast and cured 24 hr in open molds, in still air at 40 C (104 F) and 45 percent R.H. and mortars cast and cured 24 hr in closed molds at temperatures ranging from 15 C (59 F) to 45 C (113 F).
