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.

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.

2) poor communication between the fabricators and erectors. (3) The most common causes of structural failures are: (1) Poor communication between the various design professionals involved, e.g. engineers involved in conceptual design and those involved in the supervision of execution of works. (2)

Encase the beams by concrete. The beams connecting these columns were encased with 75mm thick micro concrete. Provide 8m long structural steal beam below the existing beam. But this option was rejected as the steel beam was affecting the head room in the floor. This option was also affecting the head room and was too costly.

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.

These fixings generally take the form of concrete nibs or metal (usually stainless steel) angles. Restraint fixings are designed to hold panels back and transfer all horizontal forces (such as wind pressure or suction) to the structure.
