The invention relates to a high-strength ceramsite prepared from industrial wastes, and also relates to a preparation method of the high-strength ceramsite. The ceramsite is characterized by being prepared from the following raw materials in parts by mass: 30-50 parts of polluted soil, 30-45 parts of waste salt mixed slag, 10-20 parts of power plant fly ash, 15-25 parts of surface treatment sludge, 3-10 parts of sodium silicate and 5-10 parts of putty powder. The ceramsite is prepared by the following steps: proportionally mixing the raw materials, granulating, aging, and sintering at high temperature. The method disclosed by the invention has the advantages that the method not only can solve the treatment problem of various solid wastes, but also realizes recycling of resources, and the prepared ceramsite is high in strength which can reach 16MPa or above, is uniform and compact in material, is not easy to corrode by acid and alkali, and has the characteristics of compression resistance, alkali resistance, acid resistance and the like.
本发明涉及一种利用工业废弃物制备的高强陶粒，还涉及一种制备该高强陶粒的方法，其特征在于：所述陶粒采用的原料为：污染土30～50质量份，废盐混合渣30～45质量份，电厂飞灰10～20质量份，表面处理污泥15～25质量份，硅酸钠3～10质量份，腻子粉5～10质量份，所述陶粒先经原料配比混合后进行造粒，再进行陈化，最后采用高温烧结得到。本发明优点是：本方法既能够解决多种固废的处理问题，又实现了资源的循坏再利用，且制得的陶粒强度高，可达16MPa以上，且材料均匀致密，不易酸碱腐蚀，具有抗压、抗碱、抗酸等特点。
