SLURRY QUICK HARDENING AGENT FOR WET SPRAYING MATERIAL AND WET SPRAYING CONSTRUCTION METHOD USING THE SAME
PROBLEM TO BE SOLVED: To provide a quick hardening agent having no generation of jamming of the quick hardening agent in a feed tube and jamming of a monolithic refractory in a nozzle part, while suppressing dropping or falling of a construction body during spraying in a wet spraying construction, and having no solidification of a quick hardening component even after long time storage, and a wet spraying construction method using the quick hardening agent.SOLUTION: There are provided a slurry quick hardening agent for wet spraying material, used for a wet spraying construction method, containing calcium hydroxide, a compound having effect for reducing an aggregation effect of calcium hydroxide and water, and a wet spraying construction method for adding and spraying the quick hardening agent with a spraying nozzle tip when a monolithic refractory which is mixed in advance is forcibly fed and prayed, using the quick hardening agent as a quick hardening agent.SELECTED DRAWING: None
【課題】湿式吹き付け施工において、吹き付け時の施工体のタレや落下を抑制しつつ、急結剤の供給管内での詰りや、不定形耐火物のノズル部での詰まりが生じない上に、長期間保管しても急結成分の固化が生じない急結剤、及びその急結剤を使用した湿式吹き付け施工方法を提供すること。【解決手段】湿式吹き付け施工方法に用いられるスラリー急結剤であって、水酸化カルシウムと、水酸化カルシウムの凝集作用を低減する作用を有する化合物と、水とを含むことを特徴とする湿式吹き付け材用スラリー急結剤、及び予め混練した不定形耐火物を圧送して吹き付ける際、吹き付けノズル先で急結剤を添加して吹き付ける湿式吹き付け施工方法において、急結剤として前記の急結剤を使用する湿式吹き付け施工方法。【選択図】なし
