Concrete additives for curing play a vital role in enhancing the curing process by forming a protective film over freshly poured concrete. This film effectively reduces water evaporation, maintaining optimal moisture levels essential for proper curing, particularly in hot and arid conditions. By adding SINOFLOC special concrete additives, setting time, heat of hydration, compressive and tensile strength of the concrete all give better performances, especially for hardness, the fracture toughness and flexural strength characters.
