摘　　要：通过水化程度测试、抗压强度测试、XRD及SEM分析,研究了养护温度对贝利特-硫铝酸钡钙水泥水化程度、力学性能和水化产物的组成及其结构的影响,并将实验结果与普通硅酸盐水泥的相关性能进行比较。结果表明:养护温度对贝利特-硫铝酸钡钙水泥的早期水化影响较大,适当提高养护温度对贝利特-硫铝酸钡钙水泥的早期水化具有显著的促进作用,而对后期水化影响较小。养护温度从5℃提高到35℃时,该水泥3d水化程度由31.57%提高到62.56%,水化3d抗压强度由28.1MPa增强到52.7MPa。与普通硅酸盐水泥相比,贝利特-硫铝酸钡钙水泥早期抗压强度受养护温度的影响更大。The mechanical properties,hydration degree of Belite-barium calcium sulphoaluminate cement and its composition and structure of the hydration products are studied by compressive strength testing,degree of hydration,XRD and SEM under different curing temperature at 5 ℃,20 ℃ and 35 ℃,respectively,comparing with Portland cement.The experimental results show that the influence of curing temperature on the early hydration degree of Belite-barium calcium sulphoaluminate cement is great,and appropriately increasing the curing temperature can promote the hydration of cement effectively,but little effect on latter hydration.When curing temperature increased from 5 ℃ to 35 ℃,the degree of hydration is from 31.57% to 62.56%,and the compressive strength is from 28.1 MPa to 52.7 MPa.Comparing with Portland cement,the influence of curing temperature on the early compressive strength of Belitebarium calcium sulphoaluminate cement is greater.
