Formwork is a mould including all supporting structures, used to shape and support the concrete until it is strong enough to support its own weight. In order to successfully carry out its function, formwork must achieve a balance of the following requirements:
1) Containment: The formwork must be able to form and hold the liquid concrete until it hardens. You can also consult a reliable provider for advanced concrete casting molds.
2) Resistance to leakage: All joints in the formwork must be tight or covered with molding tape to seal tightly. If grout leakage occurs the concrete will leak at that point. Leakages cause the honeycombing of the surface.
3) Accuracy: The formwork must be properly placed so that the resulting concrete product is in the right place and of the right shape and size.
4) Ease of handling: Panels and form modules should be designed so that their maximum size does not exceed those that can be easily handled manually or by machine. In addition, all formwork must also be designed and constructed to include facilities for adjustments, leveling, easing, and striking without damage to the formwork or concrete.
5) Finish and reuse potential: The material for the surface of the formwork must be selected so that it can consistently give the concrete the desired finish. At the same time, it should also achieve the required number of reuse.
Therefore, the formwork designer must not only consider the maximum number of times each formwork can be reused but also develop a design that minimizes the time required for installation and manufacture.
