Iron ore tailings, phosphate slags, and lithium slags as ternary
The high carbon emissions in the construction industry and the large-scale storage of high silicon iron ore tailings (IOTs, SiO 2 > 60% wt., Fe 2 O 3 > 10% wt.) associated with mining pose a serious challenge to sustainable development. Therefore, using IOTs as a replacement for cement to produce supplementary cementitious materials (SCMs) for concrete is a sustainable …
