| abstract | <P>PROBLEM TO BE SOLVED: To provide a cement additive restraining the expansion of a cementitious hardened material caused by the alkali-silica reaction and also of preventing deterioration of the initial strength of the cementitious hardened material even if aggregate which is determined to be "not harmless" by the alkali-silica reactivity test method for aggregates defined by JIS-A1145 is used, and to provide a cement composition. <P>SOLUTION: The cement additive contains a siliceous shale powder having an average particle diameter of 0.5-30 μm and an SiO<SB>2</SB>content of ≥75 mass%. Mortar containing the cement additive is determined to be not harmless by the alkali-silica reactivity test method for aggregate defined by JIS-A1145. <P>COPYRIGHT: (C)2010,JPO&INPIT |
