FAST-CURING GROUT COMPOSITION AND FAST-CURING GROUT
To provide a fast-curing grout composition and a fast-curing grout which has good flowability as a grout material under a low temperature environment and a high temperature environment, can maintain usable life necessary for workability, and also has excellent fast curability and short-time strength development.SOLUTION: A fast-curing grout composition includes a binder comprising cements, calcium aluminate analogs, and gypsum analogs, at least two kinds of alkali metal carbonates including lithium carbonate and sodium carbonate, and a fine aggregate, wherein an average particle diameter of lithium carbonate is 7-85 μm and an average particle diameter of sodium carbonate is 12-100 μm.SELECTED DRAWING: None
【課題】低温環境下から高温環境下においてもグラウト材としての良好な流動性を有し、作業性に必要な可使時間を確保し、且つ、速硬性及び短時間の強度発現性に優れる速硬性グラウト組成物及び速硬性グラウトを提供すること。【解決手段】セメント、カルシウムアルミネート類及び石膏類からなる結合材と、炭酸リチウム及び炭酸ナトリウムを含む少なくとも２種類のアルカリ金属炭酸塩と、細骨材と、を含み、炭酸リチウムの平均粒子径が７～８５μｍであり、炭酸ナトリウムの平均粒子径が１２～１００μｍである、速硬性グラウト組成物。【選択図】なし
