Preparation method of waste building regenerated micro powder based on constructional engineering
The invention discloses a preparation method of waste building recycled micro powder based on constructional engineering, and the preparation method comprises the following steps: preparing raw materials: waste concrete, fly ash, steel slag powder, lime powder and desulfurized gypsum, the waste concrete is repeatedly refined to obtain more sufficient and fine aggregate, and the aggregate can be recycled by utilizing different densities while being washed, so that the waste building recycled micro powder is obtained. Impurities in waste concrete are rapidly removed, materials are cleaner through preliminary washing, building waste such as plastic and wood is conveniently removed, the overall effect of later smashing is improved by controlling the drying time after washing, and therefore the overall screening efficiency is improved, meanwhile, obtained aggregate is finer, and the screening effect is better. The coarse aggregate and the fine aggregate are separated from each other, then the coarse aggregate is pulverized, more fine aggregate can be effectively obtained, and the overall pulverizing effect of the ball mill can be improved by controlling the pulverizing time and the heat treatment time of the ball mill.
本发明公开了一种基于建筑工程用废弃建筑再生微粉的制备方法，包括原料准备：废弃混凝土、粉煤灰、钢渣粉末、石灰粉以及脱硫石膏，本发明通过反复细化废弃混凝土，获得更加充分且细致的骨料，并且在水洗的同时，利用密度的不同，将废弃混凝土内部的杂质快速去除，即达到了初步水洗让物料更加洁净，又非常方便的去除塑料木头等建筑废料，并且通过控制水洗后的干燥时间，来提高后期粉碎的整体效果，从而提高整体的筛选效率，同时获得的骨料越细致，将粗细骨料相互分离，再对粗骨料进行碾碎，能够有效得到更多细骨料，通过控制球磨机的粉碎时间以及热处理的时间，能够提高球磨机整体的粉碎效果。
