Concrete Floor Slab Construction Process
- Assemble and Erect Formwork
- Prepare and Place Reinforcement
- Pour, Compact and Finish Concrete
- Curing Concrete and Remove Formwork
1. Assemble and Erect Formwork for SlabThe formwork shall be designed to withstand construction loads such as fresh concrete pressure and weight of workers and operators and their machines. Guide to Formwork for Concrete ACI 347-04 shall be followed for the design of formworks. Moreover, there are various construction aspects that need to be considered during the erection of formworks. For example, it should be positioned correctly, lined and levelled, joints sealed adequately, and prevent protruding of nails into the concrete etc... Furthermore, different materials such as wood, steel, and aluminum can be used for the formworks of concrete floor slab. Finally, there are several common formwork construction deficiencies that site engineer needs to be aware of and prevent their occurrence otherwise formwork failure may occur. These construction deficiencies are provided below:
- Poor or lack of formwork examination during and after concrete placement to identify uncommon deflections or other indications of possible failure that could be corrected
- Inadequate nailing, bolting, welding, or fastening
- Improper lateral bracing
- Construct formwork that does not comply with form drawings
- Lack of proper field inspection to ensure that form design has been properly interpreted by form builders
- Use of damaged or inferior lumber having lower strength than needed.
