2. When mixing concrete, add water or water to cool the crushed stone to reduce the pouring temperature of concrete.
3. When pouring concrete in hot weather, reduce the pouring thickness and use the pouring elevation to dissipate heat.
4. Bury the water pipe in concrete and cool people with cold water.

Maintenance of concrete:
The purpose of curing is to create suitable temperature and humidity conditions to ensure or accelerate the normal hardening of concrete. Different curing methods have different effects on concrete performance. Common curing methods include natural curing, steam curing, dry-wet curing, autoclaving curing, electric heating curing, infrared curing and solar curing. The time of maintenance experience is called maintenance cycle.
In order to facilitate comparison, it is stipulated that the specimens for measuring concrete performance must be cured under standard conditions. The standard curing conditions adopted in China are: the temperature is 20 2℃; ; Humidity is not less than 95%.
Concrete temperature control reasons:
Mass concrete technology is widely used in modern engineering technology. Because of its large volume and small surface area coefficient, the hydration heat of cement is released intensively and the internal temperature rises rapidly, which leads to a large temperature difference between the inside and outside of concrete. When the temperature difference between the inside and outside of concrete is large, it will cause temperature cracks in concrete and affect the safety and normal use of the structure.
Although we have taken various measures in the construction, cracks still appear from time to time. Therefore, temperature cracks can only be effectively prevented if temperature control is done well in mass concrete construction.
