摘要
尝试用数种化学试剂作为矿渣助磨剂,以评定它们的助磨效果。每种试剂都在完全相同的粉磨条件下与矿渣共磨,每隔一定时间测其比表面积并与矿渣空白样对比;之后对其中掺入有效助磨剂粉磨得到的矿粉试样进行激光粒度分析和图像分析仪的颗粒形貌分析;同时,又研究了助磨剂对矿渣-水泥体系标准稠度用水量、凝结时间、胶砂强度等各项性能的影响。并对有效助磨剂的合适掺量进行探索。
Several kinds of chemical agents were used as slag grinding aid to study their grinding effects.Every agent was added to slag which was grinded in the same condition.Specific areas of slag with grinding acid were tested after certain grinding time and compared with that of the slag without grinding aid.The samples which were grinded with effctive aid were analyzed by laser granulometer and image analysis.Furthermore water requirement of normal consistency,setting time and morter strength of the samples were tested.The suitable addition content of the grinding aid was also studied.
