The duration and type of curing plays a big role in determining the required materials necessary to achieve the high level of quality. Curing is the process in which the concrete is protected from loss of moisture and kept within a reasonable temperature range.The result of this process is increased strength and decreased permeability.Curing is also a key player in mitigating cracks in the concrete, which severely impacts durability.Cracks allow open access for harmful materials to bypass the low permeability concrete near the surface.uring compounds should be applied to pavements as soon as possible after bleed water has left the surface of the concrete at a rate of 200 ft 2 /gal for standard mixtures and application, 150 ft 2 /gal for fast track paving, and 100 ft 2 /gal for slabs thinner than 5.0 inches.
