Lightweight unfired artificial aggregate prepared from construction waste regenerated micro powder and preparation method of lightweight unfired artificial aggregate
The invention discloses a lightweight unfired artificial aggregate prepared from construction waste recycled micro powder and a preparation method thereof, and the lightweight unfired artificial aggregate comprises the following components in parts by mass: 1-4 parts of recycled brick powder, 1-4 parts of recycled concrete powder, 3-7 parts of a cementing agent, 0.03-0.05 part of a foaming agent mother solution, and 4.5-4.7 parts of water. Mixing the foaming agent mother liquor with water, and preparing the mixture into foam by using a cement foaming machine; mixing the cementing agent, the regenerated brick powder and the regenerated concrete powder together, adding water, and uniformly stirring to obtain slurry A; adding foam prepared in advance into the slurry A to prepare foam slurry B; injecting the foam slurry B into a spherical mold through a pastry bag, covering a plastic film, performing dry heat curing in a drying oven, and removing the mold; soaking and curing the prepared artificial aggregate for 24 hours, taking out, and naturally curing for 28 days, so as to obtain the light unfired artificial aggregate prepared from the mixed construction waste regenerated micro powder. The cost is low, solid waste resources are efficiently utilized, the prepared sintering-free artificial aggregate is lighter, and the strength meets the standard requirement.
本发明公开了一种采用建筑垃圾再生微粉制备的轻质免烧人造骨料及其制备方法，按照质量份数，包括以下组分：再生砖粉1‑4份、再生混凝土粉1‑4份、胶结剂3‑7份、发泡剂母液0.03‑0.05份、水4.5‑4.7份。将发泡剂母液与水复掺，用水泥发泡机将其制备成泡沫；将胶结剂、再生砖粉、再生混凝土粉混合在一起后，加入水搅拌均匀制得浆体A；取提前制好的泡沫加入到浆体A中制得泡沫浆体B；泡沫浆体B通过裱花袋注入球形模具中，覆上塑料膜，烘箱干热养护后拆模；将制得人造骨料浸水养护24h，取出后自然养护至28d，得到混杂建筑垃圾再生微粉制备的轻质免烧人造骨料。本发明成本低，并高效利用固体废弃物资源，制得的免烧结人造骨料更加轻质，且强度符合规范要求。
