As per IS 456: 2000 clause 11.3,
* The formwork from the underside/soffit of the slab is removed after 3 days.
* For slabs spanning up to 4.5 m, their props can be removed after 7 days.
* For slabs spanning over 4.5 m, their props can be removed after 14 days.
So, the answer should be 3 days.
* The formwork from the underside/soffit of the slab is removed after 3 days.
* For slabs spanning up to 4.5 m, their props can be removed after 7 days.
* For slabs spanning over 4.5 m, their props can be removed after 14 days.

It depends upon the span length of the slab as the span of the slab is,
1) Less than the 5 m =07 days of curing.
2) Exceeding 5 m=14 days of curing.
1) Less than the 5 m =07 days of curing.
2) Exceeding 5 m=14 days of curing.

With props or without props?
Because without props it is 3 days. And with props, if span up to 4.5 m it is 7 days and greater than 4.5 m it is 14 days.
