“…However, its market competitiveness of glass ceramics is not strong due to its complex process and high energy consumption. Chukwudi et al [9] studied the sintering properties of the materials with kaolinite, clay and steel slag as aggregates and the results showed that the ceramic bricks prepared with 20%-60% steel slag had good properties. Zong [10] et al prepared high value-added ceramics with steel slag and chemical substances such as SiO 2 and MgO as raw materials, but the content of steel slag was less than 30%.…”

In this paper, silicate-based sintering materials (SBSM) were prepared by high-temperature sintering process used steel slag as the main raw material. By strictly controlling the particle gradation of steel slag, the content of steel slag in SBSM was increased to 70%, to realize the efficient resource utilization of steel slag. The phase composition and micro-morphology of the SBSM were characterized by X-ray diffraction (XRD) and scanning electron microscope (SEM), respectively. The flexural and compressive strength of the SBSM was tested by the full-automatic compression and folding machine. The results show that the main phases of the SBSM are anorthite and quartz, and the existence of anorthite is benefit to improve the mechanical properties of the SBSM. An appropriate proportion of small-size steel slag (more than 100 mesh) can promote the reaction process, and improve the flexural and compression strength of the samples. However, the excessive amount of steel slag with small-size particles lead to a large amount of liquid phase in the reaction process, which makes the aggregate react with the matrix. This leads to the aggregate can not prevent crack propagation, so that the ability to resist external forces is reduced, and the strength of the sample is reduced. The water absorption of the samples decreases with the increase of the steel slag with small-size particles.

“…Beshr et al [15] compared how the compressive strength, tensile strength and elastic modulus of high-strength concrete are affected by four coarse aggregates, namely, limestone, dolomite, quartzite and steel slag. Chukwudi and Okorie [16] treated ceramic tiles with kaolinite clay and steel slag, revealing that the sample tiles containing 20-60wt% steel slag have good performance.…”

With the proliferation of wet milling and magnetic separation, a huge amount of steel slag mud has been discharged, waiting to be recycled. To recycle steel slag mud on a largescale, a possible solution is to prepare steel slag and other industrial solid wastes into mine filling materials. In this paper, the steel slag mud is activated through mechanochemical activation, and the mechanical activation laws are explored through X-ray diffraction (XRD) and Fourier-transform infrared spectroscopy (FT-IR). The results show that mechanochemical activation can partially excite the activity of steel slag mud, and that the fineness of steel slag mud is positively correlated with the mechanical performance of the filling material. In addition, the low field nuclear magnetic resonance (NMR) was adopted to analyze how the fineness of steel slag mud affects the porosity distribution of the filling material, and disclose the relationship between fineness and the material strength. The analysis shows that the mine filling materials prepared from steel slag mud, slag and flue gas desulfurization gypsum (FGDG) fully satisfy the required working performance. The research findings lay a theoretical basis for recycling steel slag mud, solves the environmental pollution of this type of industrial solid waste and reduces the filling cost of mine enterprises.
