Method of statement of free flow concrete with details step by step procedure.

A method statement for free-flow concrete is a detailed plan that outlines the procedures and steps involved in the installation of free-flow concrete. The following is a general outline of the procedure for installing free-flow concrete:

1. Surface Preparation: The first step in the installation of free-flow concrete is to prepare the surface. This may involve removing any existing flooring, cleaning the surface to remove dirt and debris, and repairing any cracks or other surface imperfections.
2. Formwork: The formwork should be erected to contain the free-flow concrete. The formwork should be checked to ensure that it is level and plumb.
3. Mix Design: The mix design for the free-flow concrete should be determined based on the specific requirements of the project. The mix design should be optimized to achieve the desired strength, workability, and flowability characteristics.
4. Batching and Mixing: The free-flow concrete should be batching and mixed according to the mix design. The concrete should be mixed thoroughly to ensure that it is homogeneous.
5. Placement: The free-flow concrete should be placed into the formwork using a pump or a conveyor system. The concrete should be placed in a manner that ensures that it flows freely into all parts of the formwork.
6. Compaction: No compaction is required for free-flow concrete as it is designed to flow and compact on its own.
7. Finishing: Once the free-flow concrete has been placed, it should be finished using a trowel or other finishing tool to create a smooth surface. Any surface imperfections should be corrected at this stage.
8. Curing: The free-flow concrete should be allowed to cure for the recommended time period, which is typically 7 to 14 days. During this time, the surface should be kept moist to help the concrete harden properly.
9. Sealing: After the free-flow concrete has cured, it should be sealed to protect it from moisture and other environmental factors. A suitable sealer should be applied in accordance with the manufacturer’s instructions.

It is important to follow the manufacturer’s instructions carefully when installing free-flow concrete to ensure that the finished product meets the desired performance specifications. The method statement should also be reviewed by a qualified professional to ensure that it complies with any relevant codes and standards.
