Study on Surface Pressure of High-Pressure Water.

Part3. Survey on Relations of Washing Conditions and damage of roof materials.

Abstract

In former papers, the authors reported about influence of each washing factor on washing pressure, and on the relation between the decontamination effect and washing pressure in the event concrete side and asphalt side was used. This paper describes influence on the ease of damaging to roof materials by washing conditions, and on the ease of being damaged of roof material. Moreover, the relation between washing pressure and the degree of ease of roof materials by washing conditions was considered.
