CONCRETE CURING METHODS

The Constructor

Both the rate and degree of hydration, and the resulting strength of the final concrete, depend on the curing process that follows placing and consolidating the plastic concrete. This reaction, called hydration, produces a stone-like substance—the hardened cement paste.

MATERIALS FOR FORMWORK

The Constructor

Thicker plywood may be used when the weight of concrete causes a standard thickness plywood to bow out, distorting the concrete face. Steel: Steel is also used in pre-fabricated formwork. Purpose made steel forms are fabricated when dimensional tolerances are critical, or when the forms are planned to be re-used.

FORMWORK AND GOOD FORMWORK PROPERTIES

The Constructor

When concrete is fresh and in its liquid state it must be restrained within a mould in order for it to set in its required shape. A smooth outer surface provides the main support for the concrete as it sets. Concrete is approximately 2.4 Formwork is the term used to describe this mould. This is normally made of plywood.
