| 摘要: |
| 采用浆体相对密实度（d/d0)指标，定量分析了超细磨粉煤灰，磨细矿渣及硅粉这三种矿物掺合料对新抖水泥浆体密实性能影响的规律，研究了掺矿物掺合料的水泥浆体流动性与相对密实度的关系以及新抖水泥浆体相对密实度对水泥胶砂抗压强度的影响，并进一步阐明了矿物掺合料对水泥浆体的物理填充作用。 |

| Abstract: |
| The effects of mineral admixtures ultra fine pulverized fly ash, pulverized slag and silica fume on the denseness of fresh cement paste were quantitatively studied with the index of relative denseness. The relationship between the fluidity of fresh cement paste containing mineral admixtures and relative denseness, as well as the influence of relative denseness on compressive strength of mortar are analyzed to expect to further expound the physical filling effect of mineral admixtures. |
| Key words: mineral admixtures,relative denseness,filling effect |
