MINERAL SUBSTANCE PREVENTED FROM UNDERGOING BASIC REACTION AND METHOD OF PREVENTING SAID REACTION

摘要

Mineral substances preventing base reaction and methods of preventing the reaction;According to the present invention, a mineral substance containing silica and / or silicate reactive with a basic component is contacted with hydrogen peroxide and / or ozone in the presence of water to substantially change the reaction site of the mineral substance, thereby substantially preventing the reaction with the base. A mineral material and a method for preventing the reaction thereof are provided.;As the reactive mineral substance, aggregates for hydraulic cement and silicate ceramics are exemplified. The same effect can be achieved by the presence of hydrogen peroxide and / or ozone in cement concrete materials consisting of basic reactive aggregates, hydraulic cements and water. The present invention is also useful for long-term stabilization and contamination prevention of reactive minerals coexisting with basic components.
