【摘要】：通过测试矿渣微粉筛余,比表面积和粒度分布,研究3种三乙醇胺系助磨剂对矿渣粉磨的作用效果,同时利用粒度粒形检测仪和扫描电镜分析了矿渣微粉的颗粒群形貌,并探讨了助磨剂对矿渣微粉活性指数及水泥-矿渣基胶凝材料标准稠度、凝结时间和安定性的影响。结果表明:三种助磨剂均能不同程度降低矿渣微粉筛余,提高其比表面积,提高幅度为5.3%~13.5%;掺入助磨剂后,矿渣微粉颗粒群的圆度降低,粗糙度与伸长度增加,粒度分布发生变化,0~20μm颗粒含量显著增加;水泥-矿渣基胶凝材料凝结时间缩短,标准稠度变化不大,安定性符合国家标准;助磨剂能显著提高矿渣微粉的活性指数,提升其质量等级。三种助磨剂以三乙醇胺复配无机盐的效果最好。
[Abstract]:Through the test of slag powder sieve residue, specific surface area and particle size distribution of 3 kinds of triethanolamine grinding effect on slag grinding agent, at the same time using the particle size of slag powder particles morphology analysis instrument and scanning electron microscope, and discusses the grinding of slag micro powder and cement slag activity index cementitious material standard consistency, setting time and stability. The results showed that three kinds of grinding aids have reduced slag residue, increasing the specific surface area increased by 5.3%~13.5%; adding grinding aids, slag powder particles to reduce the roughness and roundness. Elongation increased, particle size distribution changes, 0~20 m particles content increased significantly; cement slag based cementitious material of standard consistency setting time, little change, stability in line with national standards; grinding agent can significantly improve the activity index of slag powder To improve the quality grade. The three kinds of grinding aids with triethanolamine have the best effect on the inorganic salt.
