摘　　要：以再生微粉、钢渣、矿渣和脱硫石膏为主要原材料,外掺少量复合激发剂,配制出无熟料固化剂。该无熟料固化剂的物理力学性能满足32.5复合水泥的技术要求。分别对无熟料固化剂和32.5复合水泥的固化土进行不同掺量和不同龄期的抗拉强度、无侧限抗压强度、压缩性能和抗剪性能等的工程特性研究。结果表明,再生微粉无熟料钢渣固化剂掺入比为25%的固化土的工程特性相当于水泥固化土中32.5复合水泥掺入比为17%。This study uses recycled powder, slag, cinder and FGD as main raw materials, and adds a small amount of composite activator to create a new non-clinker curing agent, the physical properties of which meet the demand of cement No. 32.5. Then, a study is conducted on tensile strength, unconfined compressive strength, compression performance and shear behavior of the stabilized-soil cured by the new curing agent and 32. 5 composite cement respectively with different content and age. The result shows that the engineering characteristics of stabilized-soil cured by curing agent with a mixing ratio of 25% is equal to that cured by 32.5 composite cement with a mixing ratio of 17%.
