| 中文摘要: |
| 将石灰石和水泥熟料按不同比例混合共同粉磨，运用灰色关联分析方法，研究了石灰石水泥颗粒分布对强度的影响，并建立了28 d抗压强度与0～40μm颗粒含量的GM（1，2）灰色模型。研究结果表明：石灰石水泥粉体中10～20μm的颗粒含量与3 d强度的关联度最大，20～30μm对28 d强度影响最大。 |
| 英文摘要: |
| Limestone and clinker with different proportion were mixed. The influence of particle size distribution on strength of cement pastes was studied by grey correlation analysis. The gray model of GM(1,2) was established between 28 d compressive strength and 0~40μm particle contents. The result shows that the mass fraction of 10~20μm particle has a maximum effect on 3d strength of Portland limestone cement, and 20~30μm particle has a maximum effect on 28 d strength. |
