ROCK WOOL AGGREGATE, ROCK WOOL SPRAY METHOD, AND QUALITY EVALUATION METHOD FOR ROCK WOOL AGGREGATE IN ROCK WOOL SPRAY METHOD
PROBLEM TO BE SOLVED: To provide a technique with improved rock wool spray workability.SOLUTION: A technique has a process to form a rock wool coating layer by a semidry spray method using at least a rock wool aggregate, cement and water. The rock wool aggregate used in this process satisfies a condition that when 50 g of the rock wool aggregate put in a stainless steel cylindrical container (inner diameter: 220 mm, depth: 300 mm, thickness: 5 mm) is agitated for one minute by a hand mixer made by Ryobi (rotating speed: 850 rpm), the increment of the rock wool smaller than 1 mm is 10 wt.% or less.SELECTED DRAWING: None
【課題】ロックウール吹付作業性が向上した技術を提供することである。【解決手段】ステンレス鋼製円筒容器（内径：２２０ｍｍ、深さ：３００ｍｍ、厚さ：５ｍｍ）内に投入された５０ｇのロックウール集合体がリョービ社製のハンドミキサー（回転数：８５０回転／分）で１分間撹拌された時における１ｍｍ未満のロックウールの増加量が１０ｗｔ％以下であるロックウール集合体とセメントと水とが少なくとも用いられた半乾式工法によるロックウール被覆層が形成される工程を具備する。【選択図】なし
