The Importance Of Curing Concrete | Maha Cement

Curing is the process of controlling moisture loss from concrete that has already been placed. Curing ensures hydration of the cement, which in turn enhances it, s strength and durability. Curing takes place immediately after placing of the concrete and deals with maintenance of the desired temperature and moisture for extended periods of time.
