摘　　要：以工业废渣粉煤灰作为配制EPS板基体材料地聚合物的主要原料,磷渣作为调节基体体系凝结硬化的掺合料,用正交试验分析了磷渣掺量、细度等因素对粉煤灰地聚合物材料基体强度的影响,获得了该材料的优化配合比及其主要影响因素。在制备的基体材料中加入作为主要轻骨料的废弃聚苯乙烯泡沫颗粒,制备了具有不同密度的EPS板,并对其性能进行了测试。实验结果表明,体系中碱激发剂的模数和养护制度对地聚合物基体材料的强度影响较大。当磷渣的细度为17μm(中位径),掺量为10%,激发剂中R2O的含量为9%,激发剂的模数为1.2,养护制度为60℃蒸养时配制的材料性能最优。In this paper, industrial waste fly ash-was used as the main raw materials for preparing geopolymer-based EPS board, and the phosphorus slag was used as the additive for regulating geopolymer system condensing and hardening. The main influencing factors, such as content and fineness of phosphorus slag, on the properties of fly ash-based geopolymer were investigated by the orthogoual experimental method, and the optimum mix proportion of the fly ash-based geopolymer and its main influencing factors were determined. The EPS boards of different densities were prepared by adding waste EPS foam particles as lightweight aggregates in the fly ash-based geopolymer and their properties were tested. The experiment results show that the curing regime and the modulus of alkali activator are the main factors having relatively bigger impact on the strength of the EPS board substrate material. The material got the optimum performance when the phosphorous slag fineness is 17 micrometer （medium diameter）, content is 10%, content of Na2O in activator is 9%, modulus of activator is 1.2 and the curing regime is 60 ℃.
