| Abstract: | The packing density of cement-based materials has great effects on the workability, strength and durability of paste, mortar or concrete. Based on theories of close packing ,the different characterization methods of cement-based materials packing density are compared. From particle shape, particle size and particle size distribution three aspects, key factors which affect the cement-based materials packing density are analyzed, and the existing questions in the study are also pointed out. |
