The Fineness of a Liming Material

What is the fineness of a liming material that passes through a 100-mesh sieve and an 20-mesh sieve?

What is the formula to calculate the fineness of the liming material?

Fineness of a Liming Material:

The fineness of the liming material is approximately 0.646.

To determine the fineness of the liming material, we need to calculate the percentage of material that passes through both the 100-mesh and 20-mesh sieves. Given that 76% of the material passes through the 100-mesh sieve and 85% passes through the 20-mesh sieve, we can calculate the percentage passing through both sieves by multiplying these percentages. Therefore, the fineness of the liming material is approximately 0.646.
