Aug 12, 2014· The limestone is more easily ground than the clinker, which is harder, and becomes concentrated in the finest particles. Overall fineness must be higher (for equivalent performance) for fineness of the clinker fraction to be similar to OPC. This means the production rate is slowed and some additional grinding energy is required.

Liming to Improve Soil quality USDA

The effectiveness of agricultural limestone depends on the degree of fineness because reaction rate depends on the size of the material (surface area) in contact with the soil. Agricultural limestone contains both coarse and fine materials. Many states require 75 to 100 % of the limestone to pass an 8- to 10-mesh screen and that 25%

Use of Limestone Fines to Reduce Permeability of Concrete

Traditionally, the use of limestone fines (LF) in concrete is to replace either part of the cement or part of the fine aggregate, notwithstanding this, the authors are advocating that the LF should be better used as cement paste replacement, which is expected to improve the durability and sustainability of concrete at the same time. To verify this new strategy of using LF, 9 nos. concrete
