What technical measures should be taken in mass concrete construction in hot weather?

General building construction is mainly to find ways to reduce the hydration heat:

1, making a fuss about mixing ratio, using low hydration heat cement or reducing cement dosage: adding fly ash; Reduce the amount of cement; Add additives, etc.

2. Reduce the temperature of concrete, water and coarse and fine aggregate.

3, avoid high temperature section construction.

4. Inject cold water into the buried pipeline to cool down.
