The toughness of concrete is calculated in lbs for each square inch or kilograms for every square centimetre of pressure needed to crush a sample of the given age or hardness. Concrete’s power is influenced by environmental factors, Specially temperature and humidity. If it is permitted to dry prematurely, it may possibly practical experience unequal tensile stresses that in an imperfectly hardened state can not be resisted. In the procedure called curing, the concrete is retained moist for some time right after pouring to gradual the shrinkage that happens mainly because it hardens.
