Curing of Concrete: Purposes, Period, Effects, Factors and Methods | Engineering

The concrete surfaces are kept wet for a certain period after placing of concrete so as to promote the hardening of cement. It consists of a control of temperature and of the moisture movement from and into the concrete. The term curing of concrete is used to indicate all such procedures and processes. Purposes of Curing: Following are the objects [...]
