If the concrete built with a temperature of around 10 degrees will freeze if the temperature drops to 0 degrees two days later, will it freeze?

No.

It will freeze if the temperature drops below zero 24 hours after pouring concrete. It takes 3-7 days for concrete to reach 50%-70% of the strength of concrete in low-temperature weather.

If the concrete is attacked by negative temperatures during the setting process, the hydration of the cement will be hindered, and the free water will begin to freeze and the volume will increase by 9%. This may cause the concrete to freeze and crack, seriously affecting the quality of the concrete. It is dangerous. After the concrete is frozen in the early stage and then cured at normal temperature, its strength can still increase, but it can no longer be restored to the level that has not suffered frost damage. Moreover, the earlier it is frozen, the more difficult it will be to restore strength in the later period.

Extended information:

Concrete is classified according to its use function

Structural concrete, thermal insulation concrete, decorative concrete, waterproof concrete, refractory concrete, hydraulic concrete, marine engineering Concrete, road concrete, radiation-proof concrete, etc.

Concrete is classified according to construction technology

Centrifugal concrete, vacuum concrete, grouted concrete, shotcrete, roller compacted concrete, extruded concrete, pumped concrete, etc. According to the reinforcement method, it is divided into: plain (i.e. unreinforced) concrete, reinforced concrete, steel mesh cement, fiber concrete, prestressed concrete, etc.

Concrete is classified according to the workability of the mixture

Dry hard concrete, semi-dry hard concrete, plastic concrete, fluid concrete, high fluidity concrete, fluid concrete, etc.
