CLINKER MICROSTRUCTURE RELATED TO GRINDABILITY
The ease with which a clinker can be ground depends, among other variables, on its microstructural properties. The objective of this project was to investigate this relationship. This report discusses the laboratory portion of the project, which includes clinker production in a dynamic furnace, development of a grindability test, and evaluation of experimental clinker produced under different conditions. The following conclusions were achieved through this work: 1. The laboratory dynamic furnace clinkering process is valuable in performing clinker research; it simulates the dynamics of an industrial kiln while providing control and flexibility. 2. The comparative grindability test demonstrates grindability differences between clinkers with different microstructures, simulates the mechanics of ball mill grinding, and is an easy test to perform. 3. Interpretation of clinker microstructure can be made less subjective by inserting observations into grindability equations.
