●Overview

In the field of concrete, "mesh size" is mainly used to describe the fineness of powder materials (such as cement and admixtures), and it is a key indicator that affects their activity and performance. For aggregates, the particle size distribution (grade) is used to describe. Selecting the correct material fineness is the basis for ensuring that concrete achieves the expected strength, workability and durability.
