<P>PROBLEM TO BE SOLVED: To solidify a filling blocking material that blocks a flow by filling a conduit in a short time period, and instantaneously blocking the flow in the conduit, and to maintain the blocking performance for a relatively long time period. <P>SOLUTION: The filling blocking material M that blocks the flowing in the conduit by filling the inside of the conduit 1 is a mixture of the principal agent that is an aqueous solution where an additive is added to a mixture of cement and fly ash and the solidification material that is principally composed of a silicate aqueous solution, and the material is expansive after the principal agent and the solidification material are mixed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
