The method statement for pouring concrete includes the following steps:
- Preparation: Before pouring the concrete, the formwork must be prepared and all necessary materials and equipment should be on site. This includes cement, aggregate, water, reinforcing steel, tools, and machinery such as a concrete mixer.
- Mixing the Concrete: The concrete must be mixed in a concrete mixer or by hand, following the specified mix design. The mix should be of a workable consistency that can be easily placed and compacted.
- Placing the Concrete: The concrete should be placed in the formwork in layers and compacted with a vibrating machine. The concrete should be placed evenly and compacted thoroughly to ensure a homogeneous structure with no voids or honeycombs.
- Screeding: The concrete should be leveled using a screed board, ensuring that the surface is even and smooth. The concrete should then be left to settle for a few minutes.
- Floating: The surface of the concrete should be smoothed using a float to remove any rough or uneven areas. This step also helps to close the surface pores and make the surface smooth.
- Troweling: The concrete should then be finished using a trowel to produce a smooth and level surface. The troweling should be done carefully to avoid damaging the surface or creating voids.
- Curing: After the concrete has been placed, it should be cured properly. This is done by covering the concrete with a curing compound or a damp cloth to prevent rapid moisture loss. The concrete should be left to cure for a minimum of 7 days.
- Inspection: After the curing period, the concrete should be inspected to ensure that it has hardened properly and meets the specified strength requirements. Any defects should be rectified before the formwork is removed.
- Removing Formwork: Once the concrete has hardened, the formwork can be removed. This should be done carefully to avoid damaging the concrete surface.
It is important to follow these steps carefully and in the correct order to ensure the proper pouring and curing of the concrete. It is also recommended to have a competent person supervise the pouring process and to ensure that all workers follow proper safety procedures.
