Abstract

As one of the main wastes generated by the iron and steel industry worldwide, the large‑scale stockpiling of blast furnace steel slag not only occupies land resources but also poses environmental pollution risks. Therefore, incorporating blast furnace steel slag as coarse aggregate into traditional concrete to produce modified concrete represents an important approach to realizing the resource utilization of industrial solid waste and improving concrete performance. This paper systematically elaborates on the physicochemical properties of blast furnace steel slag, reviews the history and functions of steel slag both horizontally and vertically, summarizes relevant research and project progress in this field, analyzes key problems and technical bottlenecks in current studies, and prospects the development trend of steel slag‑modified high‑strength concrete. It aims to provide a reference for subsequent related research and engineering applications.
