| 摘 要： | 将硫铝酸锶钙矿物引入到硅酸盐熟料矿物体系中,合成了阿利特-硫铝酸锶钙水泥,改善了硅酸盐水泥的性能.利用X射线衍射、扫描电镜-能谱仪和岩相等测试手段,研究了过量掺加SO3和SrO对阿利特-硫铝酸锶钙水泥性能的影响.结果表明:熟料中SO3和SrO最佳过掺量分别为50％和80％(质量分数),制得的阿利特-硫铝酸锶钙水泥的1,3,28 d抗压强度分别达到32.8,66.8,126.4 MPa,具有良好的力学性能.SO3和SrO的过量掺入促进了硫铝酸锶钙矿物的形成,且有利于阿利特在低温下的形成.

| Abstract: | Alite strontium calcium sulphoaluminate cement(ASCSC), a new type of cementitious material was synthesized by combining strontium calcium sulphoaluminate with minerals of Portland cement. The influence of excessive SO3 and SrO on the performances of this cement was studied by XRD, SEM EDS, and lithofacies. The results show that the optimal excessive mass fraction of SO3 and SrO are 50% and 80%(by mass). The compressive strength of the cement prepared under these conditions reaches 32.8, 66.8, 126.4MPa at 1,3,28d. The additions of SO3 and SrO are beneficial to increase of content of strontium calcium sulphoaluminate and promotion of the formation of alite at low temperature. |
