Graphical Construction Glossary >> Formwork. >> formwork >> Concrete Formwork
Traditionally the material used to construct and support the forms or shuttering for concrete has been timber. However new materials and techniques are being used all the time, but it would be fair to say that timber and plywood as seen in the photos on this page is still the main method for general contracting.
Above, form work being prepared for a suspended slab on a multi-story building. In this case it consists of formply on timber joists and proprietary metal props.
When the carpenters have finished and before the rebar is placed the formply is treated with form oil.
Release Oil Should not be home made (the author has seen various recipes including the use of waste sump oil) as it can leave unsightly stains. It is often sprayed onto the surface with a backpack spray. In this case care should be taken not to contaminate nearby rebar with over spray.
At the right is the underside of the same slab showing the system of supporting the concrete formwork, and more importantly the rebar and wet concrete until the concrete has set or cured.
