The subject invention provides a building material useable as a compressed solid or as a foamable product in building projects. The building material is formed from an isocyanate and an aggregate originally having a contaminant present therein. The aggregate has been processed such that the amount of the contaminant is below a predetermined level within the aggregate. The contaminants that may be present in the aggregate include inorganic contaminants, volatile organic contaminants, and synthetic organic contaminants. The aggregate may be obtained from reclaimed soil, reclaimed sediment, reclaimed sludge, reclaimed fill material, and reclaimed mine trailings.
本发明提供了一种建筑材料,可在建筑项目中用作压缩固体或发泡产品。 该建筑材料由异氰酸酯和原本含有污染物的骨料组成。 集料经过处理后,污染物的含量低于集料中的预定水平。 集料中可能存在的污染物包括无机污染物、挥发性有机污染物和合成有机污染物。 骨料可以从再生土壤、再生沉积物、再生污泥、再生填充材料和再生矿山尾矿中获得。
