| Summary: | Abstract As a common industrial solid waste, iron ore tailing sand (IOTS) has a large amount of storage, and the treatment efficiency is unsatisfactory. Scientific and reasonable incorporation of IOTS waste into concrete is one of the critical ways to realize bulk utilization and sustainable development. This paper first summarizes the basic material characteristics of IOTS, and the similarities and differences between IOTS and natural sand (NS) are compared and analyzed. Followed with a presentation of research findings on properties of IOTS concrete with respect to mix ratio, workability, mechanical properties, drying shrinkage and durability. Subsequently, the mechanical behaviors of IOTS concrete members are analyzed and summarized in terms of experimental research, theoretical analysis and numerical simulation. Eventually, the future research directions of material and component levels of IOTS concrete are reasonably prospected. These conclusions may inform the sustainable technical application of IOTS in concrete. |
