摘　　要：将锰渣代替30%水泥,再掺入化学激发剂,制成活化锰渣水泥并成型了砂浆试件,测试其力学强度,结果表明,化学激发剂可使锰渣的活性得到激发,体系的力学强度有所提高。此外,采用红外光谱分析法对化学活化锰渣-水泥复合体系的水化过程进行了试验,结果表明,在水化早期,三乙醇胺的分子结构发生了改变,说明它参与了复合体系的水化过程,促进了水化反应程度;复合激发剂FAA的引入可促进水泥熟料矿物的水化进程加快,促使水化产物大量生成,进而提高体系的早期强度。With blending chemical activator, cement pastes containing 30% activated manganese slag can be made and the mortar speciments with are moulded. The strength testing results show that chemical activator can further activate activity of manganese slag, and the mechanical strength of composite system with manganese slag and cement can be increased. Meanwhile, the hydration process of cement pastes containing manganese slag with chemical activation have been studied by infra-red spectrum analysis. The results show that at early age of hydration, the molecular structure of triethanolamine is changed, and it can be involved in the hydration process of complex system, and which can accelerate the hydration reaction. A complex activator FAA can accelerate hydration of cement clinker and make the hydration products growing in a great qualtity, which will increases the early strength of system.
