Grading of aggregate is the particle size distribution, which is determined by sieve analysis. The particle size distribution of a mass should be such that, voids between the coarse aggregate should be filled by fine aggregates. The grading of the aggregate affects the workability of concrete. When grading of aggregate is done by sieve analysis.

For fine aggregate, the following statements are true: If the fine aggregate is too coarse, harshness, bleeding and segregation may occur. If the fine aggregate is too fine, the mix will require additional water and segregation may occur. If the grading varies significantly, the workability of the fresh concrete will likely suffer as a result.
Our Sharpening Stone Grit Chart We decided to come up with a grit chart based on 10 levels. Since one person's "fine" and one manufacturer's "fine" may mean something completely different we established a 1 to 10 grit chart with 1 being the most coarse and 10 being the finest.

The cost of grinding to a higher fineness is considerable, and also the finer the cement the more rapidly it deteriorates on exposure to the atmosphere; Finer cement leads to a stronger reaction with alkali-reactive aggregate, and makes the cement paste, though not necessarily concrete, exhibit a higher shrinkage and a greater proneness to ...
The lapping paste are graded from extra coarse to extra fine. In extra coarse there are few grits of larger size abrasives, and it is used for rough lapping. In extra fine grinding paste, there are a very large number of grits of very fine particles and it is used for fine lapping. The larger the grit rating of the lapping paste, the finer is ...
