Influence of Alkaline Activators and Simulated Seawater on the Carbonation Performance of Industrial Solid Waste–Based Persulfate Cement

Abstract

AbstractSupersulfated cement (SSC) prepared from industrial solid wastes such as steel slag (SS), granulated blast furnace slag (GBFS), and phosphogypsum (PG) are promising sustainable building materials, but their resistance to carbonation is still ...An illustration shows carbonation effects on an SSC sample. A schematic shows an uncarbonized core and a carbonized perimeter, transitioning from dense to porous structure. Two SEM images show C-S-H gel and hexagonal monocarboaluminate in the uncarbonized ...
