Artificial aggregate taking waste incineration bottom ash as raw material and preparation method of artificial aggregate
The invention discloses an artificial aggregate taking waste incineration bottom ash as a raw material and a preparation method of the artificial aggregate. The preparation method comprises the steps of providing waste incineration bottom ash, and carrying out natural weathering, air drying, crushing and screening to obtain bottom ash particles with a predetermined size; and mixing the bottom ash particles, cement, mineral powder or fly ash in proportion, putting the mixture into a disc granulator for cold bonding granulation to obtain an artificial coarse aggregate blank, and curing to obtain the artificial aggregate capable of being used for concrete. The prepared artificial aggregate belongs to high-strength light coarse aggregate, is high in strength and low in water absorption rate, and can replace natural aggregate and sintered aggregate, mining of the natural aggregate and production of the sintered aggregate are greatly reduced, resources are effectively saved, and energy consumption is reduced. According to the invention, a large amount of waste incineration bottom ash can be treated, the cost is reduced, the pressure of the bottom ash on the environment is reduced, space resources are saved, extremely high economic benefits and environmental benefits are achieved, and a sustainable development production method is provided for the building industry.
本发明公开了一种以垃圾焚烧底灰为原料的人造骨料及其制备方法，所述制备方法包括如下步骤：提供垃圾焚烧底灰，经自然风化和风干、破碎、筛选后得到预定大小的底灰颗粒；将所述底灰颗粒、水泥、矿粉或粉煤灰按比例混合后投入圆盘造粒机中进行冷粘结造粒，得到人造粗骨料胚体，经养护后即得到可用于混凝土的人造骨料。本发明制备的人造骨料属于高强轻粗骨料，强度高，吸水率低，能够代替天然骨料与烧结骨料，大大减少了天然骨料的开采和烧结骨料的生产，有效的节约资源，降低耗能。本发明能大量处理垃圾焚烧底灰，既降低了成本又减少底灰对环境的压力，节约了空间资源，兼具极高的经济效益与环境效益，为建筑行业提供了一种可持续发展的生产方法。
