Abstract:<p>Mineral sequestration using solid alkaline by-products, such as steel slag, is a feasible technology to capture carbon dioxide. This silicate weathering reaction forms solid carbonates, mineralizing the atmospheric CO<sub>2</sub> into calcite, which can occur passively under ambient environmental conditions over monthly to decadal timescales. The passive mineralization of carbon dioxide in steel slag is a not well-known reaction, particularly when climate factors in… 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.
