Medium and highly sulfidic tailings are high-volume wastes that can lead to severe
environmental damage if not properly managed. Due to the high content of sulfide minerals …

The utilization of tailings for producing solid waste-based concrete can effectively mitigate
the environmental consequences stemming from tailings accumulation. However, the …

There have been limited studies on the hardening of cement containing different heavy
metals owing to differences in solidification effect. The leachability, setting time, and …

Calcium sulfoaluminate (CSA) cements are potential candidates for the conditioning of
radioactive wastes with high sodium borate concentrations. This work thus investigates early …

This work investigates the influence of lithium ions on the hydration at 25° C of two calcium
sulfoaluminate (CSA) cements comprising 0 or 10% gypsum. Small concentrations of lithium …

It has long been common practice to solidify and stabilize low-and intermediate-level
radioactive wastes with calcium silicate cements (ordinary Portland cement, or composite …

Magnesium phosphate cements (MPC) have potential applications in the solidification/
stabilization of heavy metals. In this paper, the effect of Zn ions on the early hydration …

The influence of hydroxyethyl methyl cellulose (HEMC) on the early hydration evolution of
calcium sulfoaluminate (CSA) cement within 72 h was studied by using isothermal …

In this work, the pyrolysis behavior of electric arc furnace dust (EAFD) mixed with poly (vinyl)
chloride (PVC) was studied under inert conditions. Unwashed (UW) EAFD was found to …

Two cement pastes, prepared with a ye'elimite-rich calcium sulfoaluminate binder containing
0% or 20% gypsum, were leached by water at regulated pH (7) and temperature (20° C) for …
