During concrete curing, heat preservation measures should be taken to prevent the surface temperature of the concrete from being changed drastically by environmental factors (such as exposure to sunlight, sudden drop in temperature, etc.). During the curing, the temperature difference between the core of the concrete and the surface, and between the surface and the environment should not exceed 20 กใ C. Before the construction of large-volume concrete, a strict maintenance plan should be formulated to control the temperature difference between the inside and outside of the concrete to meet the design requirements.
After the concrete is demolished in winter and hot season, if the weather changes suddenly, appropriate insulation (cold season) insulation (summer) measures should be taken to prevent the concrete from generating excessive temperature difference stress.
