Abstract:Carbide slag (CS) is a CaO‐based waste with superior CO2 capture capacity. As it is usually recycled in the form of fine powder, the pelletization of CS is indispensable for its practical application. Here, commercial Portland cement (PC) was used as a cheap binder to produce PC‐based carbide slag (PCCS) pellets and to enhance the mechanical strength of CS. The carbonation conversion of CS declined with the addition of PC, but the ability to resist sintering was improved. Prolonging the hydration time (HT) was… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
