摘要
对助磨剂LT2 0 0 3的使用效果、影响因素和作用机理进行了研究。结果表明 ,该助磨剂能够使水泥的流动性、细度和粒度分布明显改善 ,水泥 3d、2 8d的强度也有一定的提高。影响助磨剂使用效果的主要因素是助磨剂的掺量、浓度以及粉磨物料的性质和熟料的温度。添加助磨剂可以降低物料的表面硬度、防止细粉的团聚、提高流动性 。
The applied effect,influencing factors and mechanism of LT2003 grinding-aids were researched in this paper. The research results show that LT2003 grinding-aids can improve the flowability,fineness and particle-size distribution of cement,and increase the strength of 3d and 28d cement mortar. The main factors which influence the applied effect of grinding-aids are dosage and concentration of grinding-aids,characteristics of grinding materials and temperature of clinker. The grinding-aids can decrease surface rigidity of materials,prevent agglomeration of fine grains and improve the flowability of cement,and then increase the efficiency of grinding.
