Abstract:High-early-strength-concrete (HESC) made of Type III cement reaches approximately 50–70 % of its design compressivestrength in a day in ambient conditions. Experimental investigations were made in this study to observe the effects oftemperature, curing time and concrete strength on the accelerated development of compressive strength in HESC. A total of 210HESC cylinders of 100 9 200 mm were tested for different compressive strengths (30, 40 and 50 MPa) and different curingregimes (with maximum temperatures of 20, 30, 40, 50 and 60 C) at different equivalent ages (9, 12, 18, 24, 36, 100 and 168 h). From a series of regression analyses, a generalized rate-constant model was presented for the prediction of the compressivestrength of HESC at an early age for its future application in precast prestressed units with savings in steam supply. The averageand standard deviation of the ratios of the predictions to the test results were 0.97 and 0.22, respectively.
