SANDBAG AND SANDBAG MANUFACTURING METHOD
To provide a sandbag which is lightweight, is easily transported, is excellent in shape followability, is simply disposed, and prevents degeneration even when stored over a long period of time.SOLUTION: A sandbag is obtained by filling the inside of a bag having water permeability with a filler composed of (A) 30 mass% or more and 80 mass% or less of porous ceramic having a grain size by sieve classification of 75 μm or less, and (B) a clastic material having a grain size by sieve classification of more than 75 μm. (B) The clastic material contains (B') a clastic material having a grain size by sieve classification of more than 75 μm and 1,000 μm or less, 20 mass% or more of (B') the clastic material is preferably contained in the total filler, and (B) the clastic material preferably contains a porous ceramic. In (A) the porous ceramic having the grain size by sieve classification of 75 μm or less, a pore of a micrometer order having a pore diameter of more than 10 nm and 1,000 nm or less and a pore of a micrometer order having a pore diameter of more than 1 μm and 70 μm or less preferably exist.SELECTED DRAWING: None
【課題】軽量で運搬し易く、形状追随性に優れ、廃棄処分が簡単で、かつ長期保存しても変質しにくい土嚢を提供する。【解決手段】（Ａ）篩分級による粒度が７５μｍ以下の多孔質セラミックス３０質量％以上８０質量％以下と、（Ｂ）篩分級による粒度が７５μｍを超える砕屑物と、からなる充填物が、透水性を有する袋中に充填されてなる、土嚢が提供される。（Ｂ）砕屑物は、（Ｂ’）篩分級による粒度が７５μｍ超１０００μｍ以下の砕屑物を含み、前記（Ｂ’）砕屑物が充填物の全体に対して２０質量％以上含まれることが好ましく、また、前記（Ｂ）砕屑物は、多孔質セラミックスを含むことが好ましい。前記（Ａ）篩分級による粒度が７５μｍ以下の多孔質セラミックスには、孔径が１０ｎｍ超１０００ｎｍ以下のナノメートルオーダーの気孔および孔径が１μｍ超７０μｍ以下のマイクロメートルオーダーの気孔が存在することが好ましい。【選択図】なし
