Abstract Na 2 SO 4 (NS)-activated slag as a kind of alkali-activated slag (AAS) had great
development potential in low carbon cementitious materials field, because NS could be …

Red mud and phosphogypsum are staple solid wastes, with considerably large annual
emissions. Improving their comprehensive utilization is the key to addressing the large …

Commercial sodium hydroxide (NaOH) and sodium silicate (SS) have remained two of the
leading alkaline activators widely used in producing geopolymer concrete, despite some …

Bauxite residue is a high-alkaline solid waste generated during alumina production, which
greatly limits the growth of soil microorganisms and plants. Here, we developed a novel …

In this study, the use of residues from the processing of bauxite and glass powder as
precursors for the preparation of geopolymers was evaluated. The route used was an …

The bioneutralization of alkaline bauxite residues (BR) presents a significant environmental
challenge. However, this can be mitigated by generating organic acids in situ through the …

Phoshpogypsum (PG) is an industrial byproduct of the fertilizer industry typically disposed in
the sea, dams or dykes, which presents a significant environmental hazard due to elevated …

Purpose Revegetation of bauxite residue disposal areas is an effective disposal strategy for
large-scale in-situ disposal and reduction of environmental risk. The application of organic …

This study aimed to explore the chemical looping gasification (CLG) reaction characteristics
of the metal-supported composite phosphogypsum (PG) oxygen carriers (OCs) and the …

Purpose The interaction of minerals and organic matter significantly affects the stability of
organic carbon, which is key to the rehabilitation of bauxite residue. However, due to the …
