Curing plays an important role in the strength development and durability of concrete. Liquid membrane forming curing compounds are used to retard the loss of water from concrete during the early period of setting and hardening.
They are used not only for curing fresh concrete, but also for further curing of concrete after removal of formwork or after initial water curing for one or two days. The white curing compound also has the function of reducing the temperature rise in concrete exposed to the radiation from sun.
Generally, the compound is applied to the pavement surface and then the water evaporates leaving the wax or resin to form a membrane over the surface of the pavement. This membrane helps retain moisture in the concrete.
