Quality Requirements for Curing Water Concrete ...

01/09/1991  Even at 1,000 ppm, the water is still suitable for mixing water according to ASTM C 94 which gives chemical limits for wash water used as mixing water. Staining is usually caused by iron or organic matter in the curing water, not by salts. And staining from curing water is uncommon, especially where a relatively small volume of water is used.

Requirements of Water for Curing of Concrete Role of ...

The heat in concrete can only be decreased with water curing process. Water curing restores the moisture in concrete and prepares the cement to hydrate so that the concrete can attain strength. For the smooth progression of the hydration process, the relative humidity in the concrete should be arranged perfectly.
