Regenerated micro-powder concrete mixture and preparation method thereof
The invention relates to the field of concrete, in particular to a regenerated micro-powder concrete mixture and a preparation method thereof. Comprising the following steps: 1) soaking the recycled building waste in an expansion liquid for 2-4 hours, salvaging, removing floating objects, filtering, and primarily crushing filter residues to obtain a primarily recycled material; (2) treating the primary recycled material through an acid solution, an alkaline solution and an organic solvent in sequence to obtain a recycled material a; (3) crushing the recycled material a again, and sieving with a 50-100-mesh sieve to obtain regenerated micro powder; 4, 50-180 parts by weight of the recycled micro powder, 500-1000 parts by weight of aggregate, 100-200 parts by weight of a cementing material and 30-100 parts by weight of water are weighed and mixed to be uniform, and the recycled micro powder concrete mixture is obtained.The recycled micro powder concrete mixture has good strength after being coagulated and is not prone to being partially sunken when used on pavements or buildings.
本申请涉及混凝土领域，更具体地说，它涉及一种再生微粉混凝土混合料及制备方法。包括以下步骤：1）将回收的建筑废料浸泡于膨胀液中2‑4h，打捞并去除漂浮物，过滤，将滤渣进行初步粉碎，得到初步回收料；2）将初步回收料依次通过酸性溶液、碱性溶液以及有机溶剂进行处理，得到回收料a；3）将回收料a，再次进行粉碎，过筛50‑100目，得到再生微粉；4）按照重量份计，称取50‑180份再生微粉、500‑1000骨料、100‑200胶凝材料以及30‑100水混合均匀，得到再生微粉混凝土混合料，本申请的再生微粉混凝土混合料凝结后具有较好的强度，且用在路面或建筑上，不易出现部分凹陷的现象。
