forMWorK WeiGHT of ConCreTe The weight of concrete is a direct influence since hydrostatic pressure at any point in a fluid is created by the weight of the superimposed fluid. Liquid (hydrostatic) pressure is the same in all directions at a given depth in the fluid and acts at . This practical manual has all the information you need to select and pour the right mix for the job, lay out the structure, choose the right form materials, design and build the 4/5(25). In most cases, the formwork required for concrete construction is built by carpenters. Shoring and bracing support the forms that contain the wet concrete. Formwork must also support the temporary weight of material such as bundles of reinforcing steel and live loads of workers and equipment. There are three stages in formwork operations: 1.
Manual tasks The design of formwork systems can reduce the amount of manual handling required in formwork activity. To reduce manual handling risks use: precast columns and beams to minimise fixing reinforcement, erecting and stripping column formwork and pouring concrete on site - work activities carried out in a factory. formed concrete surface quality formwork for architectural concrete bridge formwork mass concrete formwork tunnel and shaft formwork special techniques in concrete construction appendix a—referenced standards and reports appendix b—notation appendix c—glossary appendix d—conversions appendix e—aci r guide.
