The power of concrete is calculated in pounds for every sq. inch or kilograms for each square centimetre of power required to crush a sample of a supplied age or hardness. Concrete’s toughness is affected by environmental aspects, Specially temperature and humidity. Whether it is allowed to dry prematurely, it may possibly encounter unequal tensile stresses that in an imperfectly hardened condition can't be resisted. In the method often known as curing, the concrete is retained moist for quite a while soon after pouring to sluggish the shrinkage that occurs because it hardens.
