The energy of concrete is measured in lbs for each sq. inch or kilograms for every square centimetre of power needed to crush a sample of the supplied age or hardness. Concrete’s energy is impacted by environmental elements, Particularly temperature and humidity. If it is here allowed to dry prematurely, it may possibly working experience unequal tensile stresses that in an imperfectly hardened point out can't be resisted. In the process known as curing, the concrete is retained damp for a long time right after pouring to slow the shrinkage that occurs since it hardens.
