Abstract: In order to solve the problems of large-scale storage, environmental pollution, dam break and other risks, and the difficulty of utilization of iron tailings in Yangjiawan tailings dam of Chengchao Mining Co., Ltd., Wuhan Iron and Steel Resources Group, the low-silicon iron tailings were used as raw materials to prepare lightweight foam concrete by chemical method. The effects of water-to-material ratio, cement dosage, foaming agent dosage and foam stabilizer dosage on the performance of foam concrete were in⁃ vestigated. Under the condition of high dosage of iron tailings of 55%, lightweight foam concrete with density of 600.08 kg/m3 and compressive strength of 1.080 MPa was prepared. It provides a scientific basis for the comprehensive utilization of a large number of low silicon iron tailings in the tailings pond.

Key words: low silicon iron tailings, foam concrete, high admixture, new building materials
