The strength of concrete is measured in pounds for every square inch or kilograms for each sq. centimetre of power needed to crush a sample of the offered age or hardness. Concrete’s energy is afflicted by environmental aspects, especially temperature and dampness. Whether it is permitted to dry prematurely, it may expertise unequal tensile stresses that within an imperfectly hardened condition cannot be resisted. In the method called curing, the concrete is stored damp for some time right after pouring to sluggish the shrinkage that occurs since it hardens.
