METHOD FOR PRODUCING AUTOCLAVE CURED LIGHTWEIGHT FOAM CONCRETE
PROBLEM TO BE SOLVED: To provide a method where, in the production of an autoclave cured lightweight foam concrete (ALC), the time from the injection of a raw material slurry to its mold into a semi-cured body allowing its cutting and forming is reduced, and ALC is produced at high productivity with high efficiency.SOLUTION: Provided is a method for producing a lightweight foam concrete where water and aluminum powder are added to the powder of solid raw material including siliceous raw material and calcareous raw material as the main raw material so as to be a slurry. The slurry is injected into a mold, foamed, and semi-cured, thereafter, the same is subjected to high temperature-high pressure water vapor curing with autoclave, and ferrosilicon powder is added by 1 to 5 wt% to the total weight of the solid raw material.
【課題】 オートクレーブ養生軽量気泡コンクリート（ＡＬＣ）を製造する際に、原料スラリーの型枠注入から切断成形が可能な半硬化体となるまでの時間を短縮し、高い生産性で効率良くＡＬＣを製造する方法を提供する。【解決手段】 主原料である珪酸質原料と石灰質原料を含む固体原料の粉末に、水とアルミニウム粉末を加えてスラリーとし、型枠に注入して発泡させると共に半硬化させた後、オートクレーブで高温高圧水蒸気養生する軽量気泡コンクリートの製造方法において、フェロシリコン粉末を固体原料の合計重量に対して１〜５重量％添加する。【選択図】 なし
