Formwork Temporary Support for Concrete – curing Almost a Temporary Building – support weight and pressure of wet concrete Major Expense $$$
Formwork Design No Leaks Support without Excessive Deflection Easily Removed - Taper No Corners, Pockets to Trap Concrete
Form Release Compound Prevents Adhesion of Concrete to Form - Oil, Wax, Plastic KEEP OFF Reinforcing Bars – effect bond between concrete and steel
FORM MATERIAL WOOD METAL PLASTIC
Reuse Formwork High Q. Surface Form = High Q. Surface Finish Conc. Formwork Texture = Concrete texture Quality of Finished Conc. – Quality of Form Top Grade Formwork for High Finish Concrete
