LOW-SHRINKAGE ULTRA-HIGH STRENGTH GROUT COMPOSITION AND LOW-SHRINKAGE ULTRA-HIGH STRENGTH GROUT
To provide a low-shrinkage ultrahigh-strength grout composition and a low-shrinkage ultrahigh-strength grout that may be kneaded even at a low water-binder ratio, has excellent fluidity, exhibits high strength development, and suppresses self-shrinkage distortion.SOLUTION: A low-shrinkage ultra-high-strength grout composition comprises a binder comprising cement, silica fume and blast furnace slag, a ferronickel slag fine aggregate and a foaming agent. The particle size of the ferronickel slag fine aggregate is 20-70 mass% of particles having a particle size of 0.15 mm or more and less than 1.2 mm, and 20-75 mass% of particles having a particle size of 1.2 mm or more and less than 4 mm with respect to the total amount of the ferronickel slag fine aggregate.SELECTED DRAWING: None
【課題】低水結合材比においても練り混ぜ可能で、流動性に優れ、高い強度発現性を示し、且つ、自己収縮ひずみが抑制された低収縮超高強度グラウト組成物及び低収縮超高強度グラウトを提供すること。【解決手段】セメント、シリカフューム及び高炉スラグからなる結合材と、フェロニッケルスラグ細骨材と、発泡剤と、を含み、フェロニッケルスラグ細骨材の粒度は、フェロニッケルスラグ細骨材全量に対し、粒径が０．１５ｍｍ以上１．２ｍｍ未満である粒子の質量割合が２０～７０質量％であり、１．２ｍｍ以上４ｍｍ未満である粒子の質量割合が２０～７５質量％である、低収縮超高強度グラウト組成物。【選択図】なし
