摘要 以不同质量的聚合甘油以及木质素磺酸钙、糖蜜和三乙醇胺作助磨剂对熟料/粉煤灰/石膏/矿渣混合的水泥进行了研粉磨,对获得的水泥粉料进行了比表面积、颗粒分布、胶砂强度测试。结果表明,聚合甘油助磨剂掺入后,水泥粉料的比表面积增大,颗粒分布在<32μm区间的含量增大,胶砂强度增强。对水泥粉料的水化产物进行表面形貌和晶体结构分析结果表明,聚合甘油的杂质不会影响水泥水化产物,同时会降低水化产物的表面粗糙度。对聚合甘油溶剂的红外透射光谱测试表明,溶剂中含有大量羟基极性基团,使得水泥粉料在粉磨过程中分离良好,增强了聚合甘油助磨剂的粉磨效果。 Using polyglycerol,calcium lignosulphonate,molasses and triethanolamine as cement grinding aids,the cements based on clinker/fly ash/slag/gypsum are grinded.The specific surface area,particle size distribution and mortar strength of the obtained cement powders are determined.The results show that incorporation of polyglycerol leads to the increase in specific surface area,the amounts of particles less than 32 μm and mortar strength of the obtained cement powders.The morphology and crystal structure of hydration products of the cement powders indicate that the impurities in the polyglycerol have little influence on the resulting hydration products of cements,and can decrease their surface roughness.The IR spectra for the solvents of polyglycerol indicate that more hydroxyl groups in the solvents are beneficial to the separation of the cement powders during the grinding process,which improves the grinding aid effect of polyglycerol.
