Method for preparing active admixture from sludge and muck
The invention discloses a method for preparing an active admixture from sludge and muck. The active admixture is prepared from the following raw materials in parts by mass: 100 parts of dried sludge, 10-22 parts of engineering muck, 3-10 parts of lime, 1.5-5.0 parts of an exciting agent and 0.15-0.50 part of a grinding aid. The preparation method comprises the following steps: mixing the dried sludge, the engineering residue soil and lime, incinerating to obtain incinerated ash, soaking the incinerated ash in water, quenching, and finally adding an exciting agent and a grinding aid, and performing grinding to obtain the product. The method has the advantages of simple process, solid waste utilization, high product activity and the like, the defects of land occupation, poor economical efficiency and the like of sludge incineration ash landfill treatment can be overcome, and the prepared product can be used as an active admixture of cement and concrete and has good social, environmental and economic benefits.
本发明公开了一种污泥协同渣土制备活性掺合料的方法，采用包括以下质量份的原料：干化污泥100份，工程渣土10～22份，石灰3～10份，激发剂1.5～5.0份，助磨剂0.15～0.50份；将干化污泥、工程渣土及石灰混合后进行焚烧获得焚烧灰渣，并对焚烧灰渣浸水急冷，最后通过加入激发剂与助磨剂粉磨制得本发明产品。本发明具有工艺简单、固废利用且产品活性高等优点，可解决污泥焚烧灰渣填埋处置占用土地且经济性差等缺点，所制备产品可作为水泥及混凝土的活性掺合料，具有良好的社会、环境及经济效益。
