GROUT MATERIAL AND GROUT INJECTION METHOD
PROBLEM TO BE SOLVED: To suppress a volume shrinkage amount without adding aluminum powder, by reducing volume shrinkage following bleeding.SOLUTION: A grout material, which is a grout material filled into a cavity or a gap on a foundation, a structure and interface between the foundation and the structure, has a first solution which is fluid suspension containing a hardening expressing material and microbial fermentation-based thickening material, and a second solution which is fluid expansion liquid containing a montmorillonite clay mineral, in which alteration into non-fluid and plastic property is carried out by mixing together the first solution and the second solution.SELECTED DRAWING: Figure 1
【課題】ブリーディングに伴う体積収縮を軽減し、アルミニウム粉末を添加することなく体積収縮量を抑える。【解決手段】本発明のグラウト材は、地盤、構造物及び地盤と構造物の境界面の空洞や隙間を充填するグラウト材において、硬化発現材及び微生物発酵系増粘材を含む流動性の懸濁液である第１溶液と、モンモリロナイト粘土鉱物を含む流動性の膨張液である第２溶液と、を有し、前記第１溶液及び第２溶液を混合することで非流動性で且つ可塑状に変質させることを特徴とする。【選択図】 図１
