202431 · In this study, molybdenum tailings undergo alkaline hydrothermal activation to serve as a precursor for synthesizing one-part geopolymers in conjunction with slag. With an 80% slag admixture, the compressive strength of the one-part geopolymer using activated molybdenum tailings reaches 44 MPa in 28 d, notably surpassing the strength …
