Curing is the maintaining of a satisfactory moisture content and temperature in concrete during its early stages so that desired properties may develop. The curing process is essential for the production of concrete that will have the desired properties. Control of moisture loss and concrete temperature may not necessary if ambient conditions are optimum; but, otherwise, curing procedures should begin as soon as required.

During the required cure time, the concrete should be protected from premature drying, excessively hot or cold temperatures.

The concept of curing concrete is often mistaken for the process of drying concrete. Curing is best described as the chemical reaction which turns the raw ingredients of a concrete mix into a man made agglomerate rock. Drying is the process of evacuating all of the excess water in the mix. This is water not used to hydrate the cement into a glue. Curing of modern concrete requires the close control of the surrounding environment with:
• Accurate Temperature Control
• Accurate Humidity Control
• Recirculation and Energy Saving
• Good Insulation
• Time in the Curing Environment
