<P>PROBLEM TO BE SOLVED: To provide a wet spraying construction method having both construction properties and working safety by using lime slurry that does contain no causic soda harmful to a human body at all as an accelerator, and solving the the problem of the workability. <P>SOLUTION: In the construction method, a monolithic refractory that is kneaded in advance by execution moisture is force-fed, and the accelerator is added to the nozzle or in front of the nozzle for spraying. Then, in the execution method, lime slurry containing calcium chloride is used as the accelerator, and the grain size of calcium hydride that is the lime constituent of the lime slurry is set 24 μm or more in a particle diameter and 70 mass%. <P>COPYRIGHT: (C)2004,JPO&NCIPI |
