| 摘 要： | 测试了掺CaF2硫铝酸锶钙水泥的抗压强度.通过热分析、X射线衍射分析和扫描电子显微镜观察,研究了CaF2对硫铝酸锶钙水泥熟料矿物形成和水化过程的影响.结果表明,当CaF2掺量为0.2%(质量分数)时,硫铝酸锶钙水泥抗压强度最高,3,28d抗压强度分别达到65.0,86.2MPa.在水泥煅烧过程中,CaF2能加速CaCO3的分解及C1.50Sr2.50A3珔S矿物的形成.此外,CaF2可以加快硫铝酸锶钙水泥的水化速率并促使水化产物CAH10转化为C3AH6.

| Abstract: | The compressive strength of calcium strontium sulphoaluminate cement with CaF2 added was tested.The influence of CaF2 on process of mineral formation and hydration of calcium strontium sulphoaluminate cement were studied by thermal analysis(DTA-TG),X-ray diffraction(XRD) and scanning electron microscopy(SEM).The results show that compressive strength of calcium strontium sulphoaluminate cement with 0.2%(by mass) of CaF2 added is optimal,the compressive strength for 3,28 d is 65.0,86.2 MPa respectively.CaF2 accelerates decomposition of CaCO3 and formation of C1.50Sr2.50A3 during sintering of clinker.Due to CaF2,hydration rate of cement is speeded up and CAH10 changes to C3AH6. |
