Precautions:
✅1. When pouring concrete into the form-work, it should not be poured into the impact form-work or the steel reinforcement cage all at once. When the concrete pouring height exceeds 2 meters, a chute should be used for discharge. In addition, it should be noted that the distance from the discharge pipe to the pouring layer should not exceed 1.5 meters.
✅2. Once the concrete arrives at the construction site, it should ideally be poured within 90 minutes to avoid cold joints during the pouring process. Furthermore, the time difference between two consecutive pours should not exceed one and a half hours, and continuous vibration with a vibrator is essential at the junction.
✅3. During the pouring process, continuous vibration with a vibrator is crucial. Vibration can be stopped when a layer of slurry appears on the concrete surface, no air bubbles are generated, and the concrete does not settle.
✅4. When the concrete pouring is nearing completion, the volume of concrete and the amount of remaining concrete should be estimated. If more is needed, the batching plant should be contacted in advance for proper scheduling and dispatch.
✅5. After the concrete pouring is complete, the surface must be leveled using a screed. After leveling, the surface should be roughened with a brush.
✅6. After the concrete surface has been troweled two or three times, it must be covered and cured promptly. Once the concrete has set, the surface should be sprayed with water to ensure it is thoroughly moistened.
✅7. After the concrete pouring and troweling are completed, it should be covered with a plastic film immediately. The surface of the plastic film should be checked frequently for water droplets. If no water droplets are found, it should be sprayed with water again. Generally, the roof slab of a third basement level or mezzanine requires approximately 7 days of curing, while the roof slab of a first basement level requires approximately 14 days.
