1Must achieve C25 or above (at least C)20 and above).
2. Water-Cement RatioNot exceeding 0.4.
The slump of the concrete mixed on-site should not exceed 5cm, and the slump of the concrete pumped should not exceed 12cm.
4. For the concrete flooring with secondary casting, the surface layer thickness should not be less than 5cm。
5. To achieve betterEffect, recommend for concreteZhong-Canada Reinforcement Mesh (Reinforcement diameter should be ≥)φ16）。
Note: Precautions for Concrete Pouring
1Pouring must be carried out sequentially in separate storage areas.Prevent uneven concrete curing.
2. To ensure the concreteThe soil has sufficient fluidity and setting retardancy, allowing for the appropriate addition of setting retardant admixture.
3. Recommend a one-time castingAs per design elevation, if not fitted with waterproofing.Films, water must be sprinkled onto them.The foundation is in a moist condition.
4. Ensure concrete is thoroughly compacted, particularly in the corners and edges.
5. As the surfaceNo Chinese content provided. Please provide the text to be translated.No content provided.
