MANUFACTURING METHOD OF XONOTLITE LIGHTWEIGHT FOAMED CONCRETE PANEL
To provide a manufacturing method of a xonotlite lightweight foamed concrete panel by which an ALC panel having higher strength can be manufactured.SOLUTION: A method comprises: a curing step of adding a metal aluminum powder to a slurry prepared by adding water to a siliceous raw material powder and a calcareous raw material powder to foam and cure the slurry; a precuring step of forming a monosulfate by performing a precuring treatment of holding a semi-cured body obtained in the curing step under a temperature condition of, for example, higher than 40°C and 80°C or lower, or a precuring treatment of adding a hydration accelerator to the semi-cured body, or both of these precuring treatments; and a hydrothermal curing step of putting an intermediate obtained in the precuring step into an autoclave to perform hydrothermal curing.SELECTED DRAWING: None
【課題】 より高い強度を有するＡＬＣパネルを製造することが可能なゾノトライト軽量気泡コンクリートパネルの製造方法を提供する。【解決手段】 ケイ酸質原料粉末、石灰質原料粉末に水を加えて調製したスラリーに金属アルミニウム粉末を添加して発泡及び硬化させる硬化工程と、該硬化工程で得た半硬化体を例えば雰囲気温度４０℃を超え８０℃以下の温度条件下で保持する前養生処理を行うか、若しくは該半硬化体に水和促進剤を添加して保持する前養生処理を行うか、又はこれら前養生処理を両方とも行うことでモノサルフェートを生成する前養生工程と、該前養生工程で得た中間体をオートクレーブに装入して水熱養生する水熱養生工程とを有する。【選択図】 なし
