De Shuttering Period as per IS 456

Forms shall not be released until the concrete has achieved a strength of at least twice the stress to which the concrete may be subjected at the time of removal of formwork.

The strength referred to shall be that of concrete using the same Cement, Aggregate and admixture. If any, with the same proportions and cured under conditions of temperature and moisture similar to those existing on the work.

While the above criteria of strength shall be the guiding factor for removal of formwork. In normal circumstances where ambient temperature does not fall below 15 degrees, Celcius and where Ordinary Portland Cement is used and adequate curing are done, Following stripping period may deem to satisfy the guideline given below.
