LIGHTWEIGHT CELLULAR CONCRETE
To provide a lightweight cellular concrete reduced in minute defects in processing surface joints (cut grooves) and having highly designable surface peeling processability.SOLUTION: A lightweight cellular concrete having a specific gravity of 0.2 or more and less than 0.45, wherein a ratio of an insoluble residue in the lightweight cellular concrete is 5 mass% or more and less than 20 mass% based on the whole solid content, and assuming that particles having a diameter of less than 10 μm in the insoluble residue are fine particles, that particles having a diameter of 10 μm or more and less than 100 μm are middle particles and that particles having a diameter of 100 μm or more are coarse particles, a content of the coarse particles in the insoluble residue is 2.0 mass% or less.SELECTED DRAWING: Figure 1
【課題】表面目地（切削溝）加工における微欠損が少なく、かつ、意匠性の高い表面剥離加工特性を有する軽量気泡コンクリートの提供。【解決手段】比重０．２以上０．４５未満の軽量気泡コンクリートであって、該軽量気泡コンクリート中の不溶残分の比率が全固形分に対し５質量％以上２０質量％未満であり、かつ、該不溶残分の粒径が１０μｍ未満のものを微粒、１０μｍ以上１００μｍ未満のものを中粒、１００μｍ以上のものを粗粒としたとき、該不溶残分中の該粗粒の含有率が２.０質量％以下であることを特徴とする軽量気泡コンクリート。【選択図】図１
