METHOD FOR DECOLORING HARDENING BODY COMPRISING BLAST FURNACE SLAG FINE PARTICLE-CONTAINING HYDRAULIC COMPOSITION
To provide a decoloring method for rapidly decoloring a hardening body comprising a blast furnace slag fine particle-containing hydraulic composition.SOLUTION: This invention relates to a decoloring method that treats, with an oxidant, a surface of a hardening body comprising a blast furnace slag fine particle-containing hydraulic composition. Preferably, the hydraulic composition contains 5 mass% or more of blast furnace slag fine particles with regard to a cement. Preferably, the hydraulic composition contains coal fine particles and a stimulating material, and the stimulating material is two or more selected from the group consisting of hydrated lime, quicklime, a lime-based expanding material, a calcium sulfoaluminate-based expanding material, and Portland cement.SELECTED DRAWING: None
【課題】高炉スラグ微粉末を含有する水硬性組成物からなる硬化体を、速やかに脱色する脱色方法を提供する。【解決手段】高炉スラグ微粉末を含有する水硬性組成物からなる硬化体の表面を、酸化剤で処理する脱色方法。水硬性組成物が、高炉スラグ微粉末をセメント中の５質量％以上含有することが望ましい。さらに、水硬性組成物が、石炭石微粉末と刺激材を含み、刺激材が、消石灰、生石灰、石灰系膨張材、カルシウムサルホアルミネート系膨張材、ポルトランドセメントの群から選ばれる２種以上であることが望ましい。【選択図】なし
