AUTOCLAVED LIGHTWEIGHT CONCRETE PANEL
PROBLEM TO BE SOLVED: To provide an autoclaved lightweight concrete panel capable of improving fire resistance performance without increasing its density and thickness.SOLUTION: In an autoclaved lightweight concrete panel 1 obtained by adding a foaming agent to slurry containing a siliceous raw material, a calcareous raw material, and water, injecting the foaming agent-added slurry into a mold to shape the slurry, and then autoclave curing lightweight cellular concrete 3 semi-cured in the mold, a radiant heat absorbing/reflecting component 2 that absorbs or reflects radiant heat is contained in an amount of 1 wt% or more and 20 wt% or less with respect to the total solid composing the lightweight cellular concrete 3.SELECTED DRAWING: Figure 1
【課題】密度や厚さを大きくすることなく耐火性能を高めることができる軽量気泡コンクリートパネルを提供する。【解決手段】珪酸質原料、石灰質原料及び水を含むスラリーに発泡剤を加え、発泡剤が加えられたスラリーを型枠に注入して成型を行い、その後、型枠内で半硬化状態になった軽量気泡コンクリートをオートクレーブ養生することで得られる軽量気泡コンクリートパネル１に於いて、該軽量気泡コンクリート３を構成する全固形分に対して、輻射熱を吸収または反射する輻射熱吸収反射成分２が１ｗｔ％以上かつ２０ｗｔ％以下含有されていること。【選択図】図１
