Regarding addition of dry Fly Ash in Cement grinding process .Regarding addition of dry Fly Ash in Cement grinding process. Dear All Experts,. I have queries related to addition of Dry Fly Ash in cement grinding process as under:- Where should we add the Dry Fly Ash in end discharge two chamber Cement mill Inlet or out let? What are the impacts of addition of Dry.process for grinding fly ash,Effect of wet- and dry-grind fly ash on the durability of concrete .The durability performance of fly ash concrete was assessed from measurements of compressive strength, drying shrinkage, chloride permeability, seawater corrosion resistance and pore structure tests. Results show that the wet-grind process narrows the particle size distribution range of fly ash and controls the particle.
