1. Optimize the mix ratio of concrete and improve the cohesion of concrete. Such as reducing the water-cement ratio, increasing the amount of cementitious materials, adding fly ash, silica powder and other mineral additives, etc.
2. Strengthen the quality control of transportation, pouring, vibration and other construction links.
3. The use of concrete anti-segregation agents can reduce water consumption without sacrificing workability, thereby reducing segregation and bleeding.
4. When pouring concrete, avoid free falling of concrete from high places. The shorter the vertical falling distance, the better.
