Strength enhancement method of ceramsite concrete wallboard

1, reduce the water cement ratio. In order to reduce the free moisture in concrete mixture, hard concrete with small water-cement ratio and less water consumption is generally used, or water reducing agent is mixed into concrete.

2. Improve the particle gradation of coarse and fine aggregates. Grain gradation of sand refers to the matching of sand grains with different particle sizes. Well-graded sand has smaller porosity, which can not only save cement, but also improve the workability of concrete mixture and improve the compactness, strength and durability of concrete.
