がある。2. Description of the Related Art At present, backfilling of excavation sites for burial and repair of sewer pipes, gas pipes and telegraph pipes, etc. is carried out by a method in which good quality soil such as mountain sand is used for compaction with a rammer. In recent years, the rapid fluidization backfilling method has attracted attention as an alternative construction method in urban streets and the like. This method involves adding water and solidifying material to the earth and sand excavated at the site, fluidizing by mixing and stirring, and backfilling without rolling, which is a merit of shortening the construction period and suppressing the amount of remaining soil. There is.

を目的とする。However, even if these solidified materials are used in the rapid fluidization backfilling method, among the above-mentioned properties required for the treated soil, the required rapid hardening property cannot be obtained. There are many. In addition, in some cases, the reactivity is so rich that the solidification reaction starts immediately after contact with the excavated earth and sand slurry, and it is difficult to secure a predetermined fluidity. As described above, conventionally, a publicly known technique has not necessarily provided a solidifying material suitable for the rapid fluidization backfilling method. An object of the present invention is to provide a solidifying material composition which solves the above conventional problems and can be suitably used in a rapid fluidization backfilling method.
