<p><P>PROBLEM TO BE SOLVED: To provide a polymer cement grouting material composition having flowability in early stages of a premix after storage as compared with a conventional polymer grouting material made by pre-mixing a re-emulsified powder resin with a liquid shrinkage reducing agent, and to provide a grouting material using the grouting material composition. <P>SOLUTION: The polymer cement grouting material composition contains portland cement, an expanding material, aggregate, the re-emulsified powder resin and the liquid shrinkage reducing agent, wherein the liquid shrinkage reducing agent is supported by one kind selected from a group comprising natural kaolin clays, synthetic kaolin, halloysite and their calcined material. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
