Role of Concrete Curing - Cement

WebSteam curing is used where early strength gain is needed and where heat is required for hydration, such as in cold weather. In prestressing and precast plants, steam at atmospheric pressure provides high early strengths, enabling rapid demolding and reuse of forms. Excessive rates of heating and cooling may result in large, harmful volumetric ... WebProperly curing concrete improves strength, durability, water tightness, and wear resistance.
