Recycled lightweight aggregate pervious concrete and preparation method thereof
The invention belongs to the technical field of recycled concrete, and discloses recycled lightweight aggregate pervious concrete and a preparation method thereof. The recycled lightweight aggregate pervious concrete is prepared from, by weight, 800-1000 parts of modified recycled lightweight aggregate, 500-1000 parts of magnetic aggregate, 350-420 parts of cement, 0-50 parts of a mineral admixture, 0.5-1 part of modified plant fine powder, 100-120 parts of water, 0.8-1.2 parts of a polycarboxylic acid type efficient water reducing agent, 15-25 parts of composite fiber and 15-20 parts of graphene oxide powder, wherein the modified recycled lightweight aggregate is obtained by modifying crushed and graded red bricks, foam concrete, aerated concrete and other lightweight aggregates, the modified plant fine powder is obtained by modifying crushed rice straw, wheat straw, corn straw, sawdust and other plant fine powder, and the composite fiber is formed by mixing plant fibers and magnetostrictive fibers. The prepared recycled lightweight aggregate pervious concrete has good strength, percolation, wave absorption and long-term water stability, and can be used as a base layer material tobe applied to road engineering construction of sponge cities.
本发明属于再生混凝土的技术领域，公开了一种再生轻骨料透水混凝土及其制备方法，按重量份计，包括以下组分：改性再生轻骨料800‑1000份，磁性骨料500‑1000份，水泥350‑420份，矿物掺合料0‑50份，改性植物细粉料0.5‑1份，水100‑120份，聚羧酸型高效减水剂0.8‑1.2份，复合纤维15‑25份，氧化石墨烯粉15‑20份。改性再生轻骨料由破碎分级的红砖、泡沫混凝土、加气混凝土等轻质骨料在改性处理后得到；改性植物细粉料由粉碎的稻草秸秆、小麦秸秆、玉米秸秆、木屑等植物细粉料改性得到；复合纤维由植物纤维与磁致伸缩纤维混合。本发明制得的再生轻骨料透水混凝土具有较好的强度、渗滤性、吸波性与长期水稳定性，可作为基层材料应用于海绵城市的道路工程建设。
