度が高すぎるといった欠点を有している。2. Description of the Related Art Conventionally, earth and sand, soil cement and the like have been used as materials used for embankment and backfilling in civil engineering and construction work. However, since the specific gravity of these materials is generally heavy, there has been a problem that slippage of the ground or large consolidation settlement occurs. As materials for solving these problems, there are styrofoam and mortar, etc., but the former has a problem in that it is soluble in organic solvents and fire resistance, and the latter is strong as a ground material such as embankment material. Has the drawback of being too expensive.

A foamed mortar in which the mixing ratio of bubbles in the foamed mortar is increased to 50% or more and the strength is suppressed to about 10 kgf / cm 2 is put to practical use. However, even with this material, there is a problem that when the groundwater or rainwater penetrates for a long period of time, its wet density increases, and the initial lightweight property is lost.

度低下を招くなど構造上の問題にもなっている。Further, since the material containing a large amount of air bubbles has a low manifestation strength in the initial stage of casting and has a low watertightness, the moisture contained therein is dissipated into the air and a dry crack is generated. In addition to the permeation of rainwater as well as the material, it causes structural deterioration such as a decrease in strength.

Foamed mortar has been developed that can develop strength of about gf / cm 2 . However, even in the case of this foamed mortar containing water glass, the problems of permeation of rainwater due to dry cracking due to initial drying and reduction in strength have not been solved under the present circumstances.
