Foam concrete with iron tailings is prepared by iron tailings, cement, fly ash, mineral admixtures with high performance, foaming agent, polypropylene fiber, polycarboxylate superplasticizer, et al. In this study, the influences on the resistance to freezing-thawing of foam concrete with iron tailings mixed with polypropylene fiber and poly-carboxylate superplasticizer were investigated, and its microstructure was observed. The results show that the resist-ance to freezing-thawing of foam concrete with iron tailings is greatly increased by adding polypropylene fiber and polycarboxylate superplasticizer, and the microstructure of pore in foam concrete is improved obviously.
