    • A method for manufacturing lightweight insulating constructional material is provided to produce the constructional material containing light aggregate obtained from drain sludge, as well as cement paste and filler, by admixing the drain sludge with specific binder selected from clay sludge, fly-ash and waste fine tailing material to form the aggregate, and combining the aggregate with cement paste and filler. The method includes the steps of: preparing lightweight aggregate by uniformly mixing 10-90wt.% of drainage sludge with the binder selected from clay sludge, fly-ash and waste fine tailing material, forming, drying, and calcining the formed materials; dry admixing the lightweight aggregate with filler; and introducing the admixture into a cement paste containing cement and water. The produced constructional material comprises: 10-25vol.% of the cement paste, 40-70vol.% of the aggregate and 20-35vol.% of the filler. The cement paste further contains 0.5-2wt. parts of a water reducing agent, 0.5-2wt. parts of a thickener and 0.5-2wt. parts of a foaming agent or a bubble forming agent.
    • 提供一种制造轻质隔热建筑材料的方法,用于通过将排水污泥与选自粘土污泥,粉煤灰和废弃物细粒的特定粘合剂混合来生产含有由排水污泥获得的轻聚集体以及水泥浆和填料的建筑材料 以形成骨料,并将骨料与水泥浆和填料混合。 该方法包括以下步骤:通过将10-90wt。%的排水污泥与选自粘土泥,粉煤灰和废细尾材的粘合剂均匀混合,成型材料成型,干燥和煅烧,制备轻质骨料; 将轻质骨料与填料干混合; 并将混合物引入含水泥和水的水泥浆中。 所生产的建筑材料包括:10-25体积%的水泥浆体,40-70体积%的聚集体和20-35体积%的填料。 该水泥浆进一步含有0.5-2wt。 部分减水剂,0.5-2wt。 部分增稠剂和0.5-2wt。 部分发泡剂或气泡形成剂。
