Curing Concrete – Normal, Hot and Cold Weather

Concrete that is allowed to dry in air will gain only 50% of the strength of continuously moist-cured concrete. Lack of water also causes the concrete to shrink, which leads to tensile stresses within the concrete. As a result, surface cracking may occur, especially if the stresses develop before the concrete attains adequate tensile strength.
