摘　　要：结合正交试验的方法研制出一种新型胶凝材料,其力学性能可以达到32.5复合水泥标准,并进一步研究了水灰比和养护条件对其影响,同时研究了其耐久性和水化热。结果表明,其抗淡水侵蚀、抗硫酸盐侵蚀和抗干湿循环的能力均较好,水化热的情况也优于32.5复合水泥和42.5普通硅酸盐水泥。With orthogonal experiment method, a new type of cementing material was developed, its mechani-cal properties meeting the 32. 5 composite cement standard. The influence of water cement ratio and curing condi-tions as well as the durability and heat of hydration were also studied. The results show that the new cementing ma-terial has good performance in resistance against water erosion, sulfate attack and dry wet circulation. The hydration heat of the new cementing materials is also better than that of the 32. 5 the composite cement and that of the 42. 5 ordinary portland cement.
