Treatment measures for pouring concrete in summer

The ultimate strength of concrete poured in a hot climate will be reduced, and the factors affecting it are:

The temperature of concrete is higher.

The condensation and early strength increase rapidly.

With the same slump, the amount of water is increased.

Treatment measures:

Water is sprinkled on the aggregate, and the aggregate is cooled by evaporation of water.

Adding retarder to concrete;

When necessary to replace part of mixing water with ice;

Adding fly ash to regulate the influence of hot climate;

Properly increase the amount of cement per cubic meter of concrete.

The hot climate reduces the air content of concrete, which makes concrete suffer some adverse effects. Mainly:

The durability of hardened concrete is worse.

The ease of mixing of concrete is reduced.

The amount of mixing is reduced.

Treatment measures:

The air content of concrete mixture is often tested.

Increase the dosage of air entraining agent.
