Type of Formwork Formwork Removal Time
Sides of Walls, Columns and Vertical faces of beam 24 hours to 48 hours (as per engineer’s decision)
Slabs (props left under) 3 days

What is beam props?

Propping is a system of structural members used temporarily to support loads during construction. The forces arising from these loads must be fully resolved, using props or columns to provide all the support needed for the work under construction, such as beams, formwork, etc.

When should shuttering be removed from Beam?

Complete slab shuttering should be removed after 10 days. Beams removal of sheeting required 8 days. Beams and arches complete removal of shuttering required 14 days. If beams and arches are of span more than 6 meter, then shuttering removal time should be 21 days.

How many days is the proper removal for slabs?

Removal of Forms

Type of Form Removal Time Period
Walls, columns and vertical sides of beams 24 to 48 hours as may be decided by the engineer-in-charge.
Slabs (props left under) 3 days
Beam soffits (props left under) 7 days
Removal of props to slabs (Spanning upto 4.5 m) 7 days

How many times shuttering can be used?

The shuttering Ply can reuse for a maximum of 10 times, and it depends upon how you use this at the site and you remove and store it, also depend upon plywood density.

How long does it take to harden concrete to remove props?

The props’ removal time to slabs that take over 4.5 meters will need about 14 days to harden. It has the same period for removing props to arches and beams that span up to 6 meters.

How long does it take for concrete forms to dry?

Wall, vertical sides of the beam, and also columns would need a removal time of about 24 to 48 hours. It can also be changed when the engineer in charge of this concrete form task has bigger forms or ways to make it dry. For the slabs type of form, people would need about 3 days for them to remove it.
