2. Is it ok to construct cement pavement in September?
On February 29th, the temperature was minus two degrees, which had little effect on the cement floor. However, if the temperature has been seriously reduced, such as below minus five degrees, in this case, the cement floor may be damaged due to early icing, so insulation measures need to be taken. Moreover, after pouring the cement floor, the curing temperature should also be increased. For example, raise it to about 10℃, and choose the way of film mulching.
Construction temperature requirements for pouring concrete
1. In general, if the temperature reaches-15 degrees, the strength of the poured concrete will be greatly affected. When pouring concrete, the mold temperature shall not be lower than 5 degrees, and the highest temperature shall not exceed 35 degrees.
2. If it is not within this reasonable temperature range, measures should be taken. If it is winter construction, antifreeze can be added, and the temperature should be kept above-15 degrees as far as possible. If it is summer, and the average construction temperature reaches more than 30 degrees, anti-high temperature measures should be taken according to the high temperature construction scheme.
