【摘要】 以硫铝酸盐水泥的主要矿物Ｃ４Ａ３Ｓ（３ＣａＯ·３Ａｌ２Ｏ３·ＣａＳＯ４）为基础，用分析纯化学试剂ＢａＣＯ３ ，ＢａＳＯ４ 对Ｃ４Ａ３Ｓ中的Ｃａ 离子进行取代，合成了一种新水泥矿物———含钡硫铝酸钙系列矿物，并研究了该系列矿物的强度发展规律． 发现该系列部分矿物的强度明显高于硫铝酸钙，并找到了最佳矿物组成点；应用Ｘ 射线衍射仪、红外光谱仪、扫描电子显微镜和差热分析等测试手段，对熟料矿物的形成和水化机理进行了初步分析研究．更多还原

【Abstract】 Based on C 4A 3S(3CaO·3Al 2O 3·CaSO 4) which is the main mineral in sulphoaluminate cement, the Ba_bearing calcium sulphoaluminate series of new cement mineral are synthesized by substitution of analytical pure chemical reagent BaCO 3, BaSO 4 for Ca ions. The strength development of the system is also studied. The result shows that the strength of the minerals is obviously higher than calcium sulphoaluminate and the optimum composition is found. In addition, we have analysed the formation and hydration mechanism of the clinkers by means of XRD, IR, SEM, DTA and so on.更多还原
