    The environment of concrete during its early age, particularly with reference to moisture content and temperature, is an important factor with respect to its future strength and durability. Even the use of the best materials in correct proportions and with good workmanship will not assure high-quality concrete if it is allowed to dry out at an early age or if it is permitted to freeze before it has satisfactorily hardened. An additional factor, also influenced by curing conditions, is that of cracking of the concrete. Teller and Bosley (1) have stated: “Shrinkage in concrete pavement slabs during and after the initial hardening period, either from loss of moisture, drop in temperature, or both, acting in conjunction with the subgrade resistance, sets up tensile stresses which cause cracks to form in the concrete.”
