Abstract:The gain of mechanical properties of a concrete with time was investigated in this study. Standard cylinder compression tests, splitting tensile tests, and pullout bond tests were made on specimens cured at 73 F (22.8 C), 55 F (12.8 C), and 35 F (1.7 C). Tests were carried out at the age of 1, 2, 3, 5, 7, 14, 28, and 42 days after casting the concrete. Statistical analyses were made to examine the possiblity of using maturity of concrete as a parameter to correlte test rsults of concrete cured at diffeent temperatures. Rate of gain of the splitting tensile strength, pullout bond strength, and elastic modulus were compared with that of compressive strength. The results how that when related to maturity, the rate of increae in the spiltting tensile strength is about the same as that of the compressive strength, whereas the rate of increase in the pullout bond strength and the modulus are slightly greater than that of the compressive strength.
