At the batch plant, concrete should be kept at 45 to 70 degrees, with the higher end of that range required for thinner concrete pours and colder outside air conditions. Lower temperatures in that range are acceptable at the plant if the air temperature is less severe and if the pour will be thicker.

How do you add slope to a concrete floor?

Measure the distance from the lowest point of the concrete floor to the perimeter and add 1/4-inch for every foot. If you want a steeper slope, take this into account and add more to each foot to achieve your goal. This is going to be the highest point of the floor when applying the mixture.
