| 中文摘要: |
| 水泥复合胶凝材料的堆积密实度将直接影响新拌净浆、砂浆、混凝土的工作性能以及硬化体的强度、耐久性。阐明了固体颗粒紧密堆积理论，比较了水泥复合胶凝材料体系堆积密实度评价方法的特点，从颗粒形状、颗粒粒径以及粒度分布3个方面，阐述了影响水泥复合胶凝材料堆积密实度的关键因素，指出了水泥复合胶凝材料密实填充效应研究存在的问题。 |
| 英文摘要: |
| 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. |
