Preparation method of high-strength ceramsite
The invention relates to the technical field of solid waste resource utilization and high-performance ceramic preparation, in particular to a preparation method of high-strength ceramsite. According to the method, urban road sweeping garbage and fly ash are adopted as raw materials, a binder and a pore forming agent are applied for combined granulation, ceramsite blanks obtained through granulation are sintered, high-strength ceramsite is finally obtained, and the strength of the high-strength ceramsite particles obtained through the method reaches 96.74-128.73 MPa; the density grade is 500-700 grade, and the 1h water absorption rate is 6.83-16.39%. According to the method, urban road sweeping garbage and fly ash are used as raw materials, the raw materials are wide in source and large in output; on one hand, the production cost of the ceramsite is reduced, on the other hand, the current situation that the resource utilization rate of the road sweeping garbage is low can be solved, the dual purposes of protecting the environment and turning waste into wealth can be achieved, and good application prospects are achieved.
本发明涉及固废资源化利用与高性能陶瓷制备技术领域，具体涉及一种高强陶粒的制备方法。本发明方法采用城市道路清扫垃圾以及粉煤灰为原料，并施以粘结剂、造孔剂联合造粒，将造粒得到的陶粒胚料进行烧成，最终得到高强度的陶粒，在经过本发明方法得到的高强陶粒颗粒强度达96.74～128.73MPa；密度等级为500～700级，1h吸水率为6.83～16.39％。本发明方法以城市道路清扫垃圾以及粉煤灰为原料，原料来源广泛，产生量大；一方面降低了陶粒的生产成本，另一方面可解决道路清扫垃圾资源化利用率低的现状，能够实现环境保护、变废为宝的双重目的，具有很好的应用前景。
