Lightweight ceramsite prepared from incineration fly ash of garbage power plant and preparation method of lightweight ceramsite
The invention discloses light ceramsite prepared from incineration fly ash of a garbage power plant, the light ceramsite is prepared from the incineration fly ash, fly ash, bentonite, rice chaff meal and other raw materials, and the preparation method sequentially comprises the process steps of material mixing, ball milling, granulation, calcination and the like. The lightweight ceramsite prepared by the invention meets the requirement of high-strength lightweight aggregate with the density grade of 600 for preparing LC25 lightweight aggregate concrete in Lightweight Aggregate and Test Method thereof GB/T 17431-2010, and meanwhile, the preparation process is simple, the cost is low, and the utilization rate of incineration fly ash is high. According to the method, waste is turned into wealth, meanwhile, a way is provided for effective resource utilization of the municipal waste incineration fly ash, environmental pollution is reduced, the purpose of saving resources is achieved, and good economic benefits and social benefits are achieved.
本申请公开了一种利用垃圾电厂焚烧飞灰制备的轻质陶粒，该轻质陶粒由焚烧飞灰、粉煤灰、膨润土、稻糠粉等原料组成，其制备方法依次包括：混料、球磨、造粒、煅烧等工艺步骤。本发明所制备的轻质陶粒达到GB/T 17431‑2010《轻集料及其试验方法》中配置LC25轻骨料混凝土、密度等级为600的高强轻集料要求，同时制备工艺简单、成本低、焚烧飞灰利用率高。本发明在变废为宝的同时，为城市垃圾焚烧飞灰有效地资源化利用提供了途径，降低了环境污染，达到了节约资源目的，具有良好的经济效益和社会效益。
