摘　　要：对地质聚合物技术做了一个简要的介绍,分别从原材料、激发剂、添加剂和养护条件四个方面对近年来国内外学者在粉煤灰基地质聚合物力学性能的影响因素方面所做的工作和研究成果进行了介绍。粉煤灰的物化特性对粉煤灰基地质聚合物的力学性能有决定性的影响;激发剂中的碱形式、碱浓度和硅含量对粉煤灰基地质聚合物的抗压强度影响较大;适当的添加剂能提高粉煤灰地质聚合物的抗压强度;相对较高的养护温度有利于粉煤灰基地质聚合物力学性能的发展。在所有的影响因素中,原材料的成分和性质是最难控制的因素。最后,对研究原材料对地质聚合物力学性能影响的研究给出了建议。In this paper, the geopolymeric technique was briefly introduced. A review of the recent researches about the factors affecting the mechanical properties of fly ash-based geopolymers was given mainly in four aspects, row sources; activators; superplastieizers and curing condition. The physical and chemical properties have dominating influences on the mechanical properties of fly ash-based geopolymers ; the concentration of alkaline and silicon have effects on the mechanical properties as well as the alkaline type ; proper superplasticizers can improve the mechanical properties of fly ash geopolymers; the relatively high curing temperature has positive influences on the development of mechanical properties of fly ash-based geopolymers. In all these factors, the row source is the most difficult to be controlled. Finally, suggestions about research the effects of row sources on the mechanical properties of geopolymer were given.
