Geometric Requirements: Aggregate Grading and Fines Content. Many engineering properties of a material, such as shear resistance, are associated with its particle grading. Thus, it is important to make sure that the particle size distribution of CS always complies with the fine aggregate grading requirement specified in the standard, particularly when crushing aircooled CS to sand ...
