1. The concrete floor just poured in hot weather can be covered with plastic film to keep the moisture in the concrete. Cover the ground with cotton cloth or straw curtain. After the initial setting of concrete, water can be sprayed to cool down and control the curing temperature.

2. In hot weather, cooling water should be used to mix concrete, ice should be used to replace part of the mixing water, and liquid nitrogen should be used to cool the mixed concrete to reduce the temperature of the concrete itself;

3, concrete pouring, try to choose at night or low temperature weather. Minimize transportation and pouring time. During this period, when the temperature rises, covering and heat preservation measures should be taken in time after pouring.

4. Before pouring concrete in hot weather, a special construction scheme must be made, and the operation and construction shall be carried out in strict accordance with the scheme. Fully considering the mixing, pouring and curing of concrete in high temperature weather will increase the cement hydration rate and humidity evaporation rate of concrete, which will adversely affect the concrete characteristics and service reliability.
