测试钢渣微粉与硅灰取代部分水泥进行胶砂试验时水泥砂浆的抗压强度,采用X射线衍射仪检测,扫描电镜对试块进行微观结构形貌观察,研究了二者取代部分水泥进行试验对砂浆的强度及胶凝性的影响。试验结果表明:钢渣微粉取代部分水泥单掺时水泥砂浆的抗压强度增长率随着龄期的增长呈上升趋势;二元复掺时,强度增长率远远大于空白组,两者复掺在20%时效果最好。在实际工程中加入钢渣微粉与硅灰,不仅可以提高砂浆的强度,而且变废为宝,为资源的可持续发展做出贡献。

To test the compressive strength of the cement mortar,the X-ray diffractometer and the scanning electron microscopy were used to observe the microstructure of the test block by testing the steel slag micropowder and silica fume to replace some cement.The strength of the mortar and the effect of gelation.The test results show that the growth rate of compressive strength of cement mortar increases with the increase of age when steel slag micropowder replaces part of cement.When binary compounding,the growth rate of strength is much larger than that of blank group.20%works best.Adding steel slag ...
