Concrete’s power is afflicted by environmental factors, Specially temperature and humidity. Whether it is permitted to dry prematurely, it can working experience unequal tensile stresses that in an imperfectly hardened state cannot be resisted. In the procedure referred to as curing, the concrete is held moist for a long time soon after pouring to sluggish the shrinkage that occurs mainly because it hardens.
