Regenerated micro-powder activation method
The invention discloses a regenerated micro-powder activation method. The method comprises the following steps: (1) selecting materials: selecting waste concrete and waste sintered bricks recovered from a construction site as regenerated micro-powder raw materials, wherein the waste concrete and the waste sintered bricks being processed separately; (2) creating an isolation area: selecting a construction area, erecting an isolation plate to seal the construction area, and installing a dust removal facility to create a construction environment; (3) performing primary crushing: performing primary crushing on the regenerated micro-powder raw material through a universal crusher; and (4) screening: screening the crushed regenerated micro-powder raw material to separate small fragments with the diameter of less than 40 mm, and taking powder with the diameter of less than 0.16 mm as initial regenerated micro-powder. The regenerated micro-powder can be collected to the maximum extent, the regenerated micro-powder is prevented from diffusing in air to form haze to pollute the atmosphere, and recycling is achieved; and the regenerated micro powder can be activated through the exciting agent and can be prepared into regenerated micro powder concrete and set cement, so the building waste is effectively and comprehensively utilized, and environmental hazards are relieved.
本发明公开了一种再生微粉活化方法，包括以下步骤：(1)选料：选用废旧混凝土和工地回收的废旧烧结砖作为再生微粉原料，所述废旧混凝土和废旧烧结砖采用单独加工方式进行；(2)创建隔离区：选择施工区域，并架设隔离板封闭施工区域，安装除尘设施营造施工环境；(3)初粉碎：通过万能破碎机对所述再生微粉原料初步粉碎；(4)筛分：对粉碎后的所述再生微粉原料筛分，分离出直径40mm以下的小碎块，直径小于0.16mm的粉料作为初始再生微粉。本发明可最大限度的收集再生微粉，既防止再生微粉弥漫在空气中形成雾霾污染大气，又实现了再利用，通过激发剂可使再生微粉活化，可制备成再生微粉混凝土和水泥石，解决建筑垃圾有效综合利用，缓解环境危害。
