What's the temperature of concrete pavement? Do you need anti-freezing treatment?

Generally speaking, when the daily average temperature of concrete construction is lower than 5 degrees for five consecutive days, it will enter winter construction, and concrete needs to be antifreeze.

It can be combined with water reducer and air entraining agent to prevent freezing, and the effect is better. Used in various concrete projects, used in cold season construction. Make the concrete hydrate normally in the negative temperature environment of 0℃ to-15℃; Reduce freezing point and improve early strength of concrete.

Extended information: Concrete cured with antifreeze shall meet the following requirements? :

1. When curing at negative temperature, watering is not allowed. After concrete pouring, it should be covered with plastic film and thermal insulation material immediately. Heat preservation measures should be strengthened in cold areas.

2. The initial curing temperature shall not be lower than the specified temperature.
