alignment.
3.02 PREPARATION OF FORM SURFACES
Coat contact surfaces of forms with a form-coating compound before reinforcement is
placed.
Thin form-coating compounds only with thinning agent of type, and in amount, and
under conditions of form-coating compound manufacturer's directions. Do not allow
excess form-coating material to accumulate tin forms or to come into contact with concrete
surfaces against with fresh concrete will be places. Apply in compliance with
manufacturer's instructions.
Coat steel forms with a non-staining, rust-preventative form oil or otherwise protect against
rusting. Rust-stained steel form work is not acceptable.
3.02 REMOVAL OF FORMS
Formwork not supporting weight of concrete, such as sides of beams, walls, columns, and
similar parts of the work, may be removed after cumulatively curing at not less than 50°F
for 24 hours after placing concrete, provided concrete is sufficiently hard to not be
damaged by form removal operations, and provided curing and protection operations are
maintained. The lift station roof must obtain design strength before the forms are
removed.
Formwork supporting weight of concrete, such as beam soffits, joints, slabs and other
structural elements, may not be removed in less than 14 days and until the concrete has
attained design minimum compressive strength at 28 days. Determine potential
compressive strength of in-place concrete by testing field-cured specimens representative
of concrete location or members.
