摘　　要：研究了复掺氟、磷离子和金属离子(水泥)熟料的抗折强度、抗压强度和岩相结构,分析了熟料主要矿物阿利特在XRD图谱指纹区的衍射特征.结果表明:当氟、磷离子掺量(以CaF2和P2O5计,质量分数)分别保持为0.7%,0.5%时,氟、磷离子和低掺量金属离子的复掺可以提高熟料的28d抗压强度,其中以氟、磷离子和低掺量锌离子的复掺效果最佳.当氟、磷离子掺量分别保持为0.7%,0.5%时,铜离子、锌离子、铅离子和钛离子的最佳掺量(以CuO,ZnO,PbO和TiO2计,质量分数)分别为0.1%,0.5%,0.5%,0.1%.氟、磷离子和金属离子在低掺量水平的复合掺杂,使熟料岩相结构缺陷增多,熟料主要矿物阿利特在指纹区的XRD图谱呈现高对称性衍射特征,这正是实现熟料高强度的重要原因.The flexural strength,compressive strength and petrographic structure of（cement）clinkers added with fluoride,phosphate ions and metallic ion were tested,and the X-ray diffraction characteristics of alites extracted from clinkers in dactylogram region were investigated.The results show that when the use levels（by mass）of fluoride,phosphate ions（based on CaF2 and P2O5）are kept at 0.7%and 0.5%,the28 dcompressive strength of clinker could be enhanced by adding fluoride,phosphate ions and a little bit of metallic ion in clinker,addition of fluoride,phosphate ions and a little bit of zinc ion in clinker appears to have the best effect.The optimal use levels（by mass）of cuprum ion,zinc ion,plumbum ion and titanium ion（based on CuO,ZnO,PbO and TiO2）are 0.1%,0.5%,0.5%,0.1%respectively when the use levels of fluoride,phosphate ions are kept at 0.7% and 0.5%.At the low use level of fluoride,phosphate ions and metallic ion,the petrographic structures of clinkers present more defect,the X-ray diffraction characteristics of alites extracted from clinkers in dactylogram region show the characteristics of higher symmetry.It is the important reason why the clinker presents higher strength.
