SUPPRESSING MATERIAL FOR ALKALI-SILICA REACTION AND METHOD FOR PRODUCING THE SAME |
摘要 |
<P>PROBLEM TO BE SOLVED: To provide a suppressing material for alkali-silica reaction producible in a short time without using an expensive lithium-based material nor causing an environmental problem. <P>SOLUTION: This method for producing a suppressing material for alkali-silica reaction includes a first stage of obtaining an alkali ion-type hardened body by polymerization reaction by mixing a material containing silica and alumina with an alkali agent, and a second stage of ion-exchanging an alkali-ion to a hydrogen ion by subjecting powder of the alkali ion-type hardened body to an acid treatment after pulverizing the alkali ion-type hardened body. <P>COPYRIGHT: (C)2013,JPO&INPIT |
