The rheologic property of these cement pastes was measured by means of the rotary viscometer,the micro slump meter cone and vicat apparatus,and the mechanisms of the influence of the ratio of sulfate and alkali content on the rheologic property of cement paste were analyzed with petrographic analysis and SEM.
模拟预分解窑煅烧制度,在电炉中烧制不同硫碱比的高碱熟料,分别对掺与不掺石膏的浆体,用旋转黏度计、微型坍落度仪以及维卡仪(测净浆针入度)等方法测其流变性能;并结合岩相分析、扫描电镜(SEM)对熟料硫碱比影响浆体流变性的机理进行分析探讨。
Analysed the ash components of 154 coal samples,discussed the influence of the main materials and acid/alkali ratio in the coal ash on ash fusibility in the paper,gained the relationship between acid/alkali ratio and ash fusibility.
通过对154个煤样的灰成分进行分析,探讨了煤灰主要成分及煤灰中酸碱比对灰熔融性的影响,并回归出了酸碱比与灰熔融性的关系式,预测结果与实测值具有较好的一致性。
