1, for portland cement concrete floor, under the condition of curing temperature of 1 degree, 10 day can only reach 33% of the standard strength; Under the condition of curing at 20 degrees, the standard strength 10 can only reach 70% in one day and 100% in 28 days. Under the curing condition of 35 degrees, 10 day can reach 86% of the standard strength, so increasing the room temperature can make the cement floor dry quickly.

2. If possible, steam or hot water can be used for health preservation, which can make the cement floor dry faster. The concrete precast component factory adopts steam curing for up to one week, and the concrete precast component reaches the standard strength.
