Preparation and Performance of Vanadium Tailings-Reservoir Sediment-Phosphogypsum-Based Foamed Concrete

Foamed concrete (FC) was prepared from raw materials of vanadium tailings (VTs), reservoir sediment (RS), and phosphogypsum (PG). The physicochemical properties of the raw materials were studied by using X-ray diffraction (XRD), X-ray fluorescence (XRF) analysis, and inductively coupled plasma emiss...
