Strength of mortar under constant curing temperature develops asymptotically to a saturated strength depending on the temperature. The higher the curing temperature is the faster the strength develops, if the temperature is in studied range. While the curing temperature is varying, the curing process must be sectioned into discrete steps. In each step, the curing temperature is assumed to be constant, the average temperature in the step. The developed strength is then calculated step by step, and accumulated to be the final strength. Experiments were conducted to verify the validity of the proposed technique.
