Method for producing concrete pavement brick by using waste FCC (fluid catalytic cracking) catalyst
The invention belongs to the field of preparation of environment-friendly building materials, and particularly relates to a method for producing a concrete pavement brick by using a waste FCC (fluid catalytic cracking) catalyst. The method comprises the following steps: (1) stirring and mixing the waste FCC catalyst and a curing agent in water, sequentially adding cement, sand, mineral powder and pebbles, and uniformly stirring to form semi-dry concrete; and (2) feeding the obtained product into a main machine hopper, carrying out material distribution in a main machine mold, carrying out vibration pressure forming and demolding, and then feeding the product into a curing kiln to carry out steam curing and curing agent curing so as to obtain a target product. According to the method, the environmental pollution can be reduced, and the treatment cost of the hazardous wastes is also reduced. The production process route of the concrete pavement brick is simple, the preparation cost is low, the operation is easy to control, the production efficiency is high, three wastes are not generated in the whole process, the popularization and application are easy, and the environmental protection is facilitated.
本发明属于环保建筑材料制备领域，具体地涉及一种利用废FCC催化剂生产混凝土路面砖的方法，包括：（1）将废FCC催化剂与固化剂在水中搅拌混合,依次加入水泥、沙子、矿石粉、石子，搅拌均匀后，形成半干性混凝土；（2）将所得产物送至主机料斗内，在主机模具中进行布料并震动加压成型脱模后，再送至养护窑进行水蒸气养护和养护剂养护后，即得目的产品。本发明不仅能减少了环境污染，而且还降低了危险废物的处理成本。混凝土路面砖的成产工艺路线简单，制备成本低，操作容易控制，具有较高的生产效率，并且整个工艺过程不产生“三废”，易于推广应用，又有利于环境保护。
