CEMENT COMPOSITION FOR ALKALI-SILICA REACTION SUPPRESSION AND CEMENT-CONTAINING COMPOSITION

摘要

PPROBLEM TO BE SOLVED: To provide a cement composition for alkali-silica reaction suppression by which the alkali-silica reaction is suppressed without adding an admixture. PSOLUTION: The cement composition for alkali-silica reaction suppression suitably comprises cement clinker and gypsum, has a composition comprising SiOSB2/SB, AlSB2/SBOSB3/SBand FeSB2/SBOSB3/SBwherein the ratio SiOSB2/SB/(AlSB2/SBOSB3/SB+FeSB2/SBOSB3/SB) is 2.5 by mass.
