In concrete floors keeping the moisture in the concrete improves the strength of the bonds near the surface which reduces the risk of delamination and increases the abrasion/wear resistance of the slab.
All the cement and combinations require effective curing to develop optimum properties in the hardened concrete. Abrasion resistance is particularly sensitive to the early drying of the surface that may occur if curing is inadequate. The early strength development of concrete containing pfa or ggbs is slower in colder weather, so proper curing is important to prevent moisture loss, which may result in surface dusting and poorer abrasion resistance. It is therefore important to apply appropriate curing techniques as soon as practical after finishing is completed
