Synergistic effect of hydration and carbonation of ladle furnace aslag on cementitious substances.

Ladle furnace slag (LFS) can undergo hydration and carbonation reactions as cement. This article explores the effect of LFS hydration and carbonation reactions on cementitious substances at different temperatures and different LFS particle sizes, determining the effect of these varying conditions on the microstructure and formation mechanism of cementitious substances. The results show that in the early stages, CS and CS undergo hydration to generate C-S-H gel, which then undergoes decalcification and condensation to generate CaCO and Ca-deficient C-S-H gel; the hydration reaction and carbonation reaction promote and influence each other.
