[PROBLEMS] A filling blocker that fills a conduit and blocks the flow, can solidify in a short time and can block the flow of the conduit instantaneously, and can maintain the blocking performance for a relatively long time. A filling blocking material M that fills a conduit 1 and blocks the flow of the conduit, and is mainly composed of an aqueous solution obtained by adding an additive to a mixture of cement and fly ash and an aqueous silicate solution. It has a mixture with the solidifying material, and has expandability after mixing the main material and the solidifying material. [Selection] Figure 4 |
