What is the impact of the concrete pavement on the quality of the pavement?

Answer:

When the concrete reaches the design strength of 25% to 30%, should be used to cut the sewing machine.
The slit is too early and the coarse aggregate will escape from the mortar; the slit is too late, and if the tensile stress is greater than the allowable value of the concrete, the concrete slab will crack.
High temperature, concrete strength growth fast, cutting time to be early.Temperature difference, cutting time should be early.
Slot time generally follow the principle of "can cut on the cut, rather early morning."Sewing machine, should adopt the model small, fast speed, small vibration, in the concrete pouring a few hours to cut.
