ABSTRACT:
A process is disclosed for fast and uniform hydration of uncured concrete products. Pressurized and superheated water is supplied to a manifold supporting a plurality of small diameter orifice nozzles housed inside a curing room which also houses the products during curing. Water is ejected by the nozzles in very fine particulate form, creating a mist or suspension of superheated water particles that surrounds the products and creates the desired high humidity, moderately high temperature environment for promoting hydration. The water preferably is softened before it is pressurized and supplied to the nozzles. Under favorable conditions, the hydration reaction supplies sufficient heat to maintain a desired temperature within the curing room, eliminating the need to heat the water before it is supplied to the nozzles.
