Concrete’s strength is affected by environmental components, Specifically temperature and moisture. If it is allowed to dry prematurely, it might working here experience unequal tensile stresses that within an imperfectly hardened condition can't be resisted. In the procedure often called curing, the concrete is stored damp for some time after pouring to sluggish the shrinkage that occurs because it hardens.
