Careful management of the entire process is known as curing. Curing insulates the moist concrete from the air, preventing the evaporation of moisture from the concrete too quickly. This allows the bonding to take place slowly and ensures that the concrete reaches its design strength and hardness.
New concrete can take three weeks to reach 90% of its final strength. Only insulation from the elements through proper curing can enable this to take place.
Modern concrete curing is facilitated through the application by a concrete-finishing specialist of a specially-designed curing compound to the surface of the fresh concrete, insulating it from the air beneath an impervious film. This insulation from the elements enables hydration to take place at an appropriate pace, moisture level, and temperature.
The insulating compounds used range from mineral-based resins to acrylic emulsions, and are selected by the concrete-finishing specialist based on the curing requirements of the concrete installation at hand.
Ignorance of the critical importance of the concrete curing process can lead some builders to take shortcuts. To cut costs some builders may use someone other than a concrete specialist to spray a sealant over freshly-laid concrete in the hope that this will achieve the same results as proper concrete curing. The sealant often fails to meet the Australian Standard for curing AS3799.
Incorrect choice of a curing compound may have detrimental effects on the strength of the concrete as well as effecting subsequent after-trades such as the adhesion of vinyl or carpet glues.
