| 中文摘要: |
| 通过矿渣，粉煤灰和石灰石三种混合材料的单掺、复掺，研究了混合材料对硫铝酸盐水泥性能的影响。研究结果表明，混合材料能够实现对硫铝酸盐水泥的改性，且复掺效果优于单掺；其机理主要是改变了钙矾石的形貌、降低了浆体的膨胀率、密实了浆体结构和减少了硬化浆体的微裂纹。 |
| 英文摘要: |
| The influence of three kinds of mixing materials(slag, fly ash and limestone) on the properties of sulphoaluminate cement was studied by adding one or two of the admixture. The results show that the the admixtures can realize the modification of sulphoaluminate cement, and the effect of adding two is better than that of single doped, and the mechanism is mainly to change the morphology of ettringite reduced the slurry expansion rate, compacting the paste structure and reduce the micro cracks of hardened paste. |
