QUICK SETTING AGENT FOR WET SPRAY MATERIAL METHOD FOR PRODUCING SAME WET SPRAY MATERIAL INCLUDING SAME AND WET SPRAY MATERIAL CONSTRUCTION METHOD

摘要

Provided are a quick-setting agent having excellent workability with which it is possible to obtain good quick- setting properties and curability, a method for producing the same, a wet spray material including the same, and a wet spray material construction method. A quick-setting agent for a wet spray material of a monolithic refractory prepared from a calcium hydroxide slurry having calcium chloride added as needed, characterized in that: the oxalic acid reactivity, sedimentation volume, and viscosity of the calcium hydroxide slurry are respectively, oxalic acid reactivity: 40 min or less, sedimentation volume: less than 60 mL, and viscosity: less than 200 mPa ・S; the total content of calcium hydroxide and calcium chloride in the quick-setting agent is less than 46 mass%; and the content ratio of calcium hydroxide to calcium chloride is within the range of 50:50-100:0.
