Abstract
In the processing area of the materials for architecture, recently, the processing of the materials for that object using the high speed liquid jet stream has been become the topic of the talk. This processing is a new method of ones using the high speed liquid jet of which velocity is about several times of sonic one in the air and by using this liquid jet, we can process the materials, namely make the relatively small holes, cut, make fracture and so on in those materials. Especially in the rock processing, this processing is for the formation of relatively smaller ditches and for the impulsive fracture of massive rock by means of high speed liquid slug. So in this report, for the purpose of clarifying the basic characteristics of this processing, we mention the principle of this processing, outline of this experimental processing device and results of application to the practical architectural rock materials.
