Recycled aggregate micro-powder concrete, preparation method and drainage road edge stone
The invention discloses recycled aggregate micro-powder concrete, a preparation method and drainage road edge stone, which relate to the technical field of building materials. The recycled aggregate micro-powder concrete provided by the invention is prepared from the following components in parts by weight: 0.5 to 0.6 part of Portland cement, 0.8 to 1.2 parts of fine aggregate, 0.8 to 1.2 parts of coarse aggregate, 0.3 to 0.4 part of recycled aggregate micro-powder, 0.2 to 0.3 part of mineral active powder, 0.3 to 0.35 part of water and 0.03 to 0.06 part of polycarboxylate superplasticizer. According to the recycled aggregate micro-powder concrete provided by the invention, the recycled aggregate micro-powder comes from building solid waste, can replace a part of cement, and is one of main raw materials for preparing road edge stones and other road buildings; by adding the mineral active powder, the mechanical property and durability of the concrete product can be improved, and the scheme can realize effective resource recycling of the building solid waste.
本发明公开了一种再生骨料微粉末混凝土、制备方法及排水路沿石，涉及建筑材料技术领域。本发明提供的再生骨料微粉末混凝土，按重量份计，包括：硅酸盐水泥0.5‑0.6份、细骨料0.8‑1.2份、粗骨料0.8‑1.2份、再生骨料微粉末0.3‑0.4份，矿物活性粉末0.2‑0.3份、水0.3‑0.35份及聚羧酸减水剂0.03‑0.06份。本发明提供的所述的再生骨料微粉末混凝土，再生骨料微粉末来源于建筑固体垃圾，可取代部分水泥用量，是制备路沿石等道路建筑的主要原材料之一；通过添加矿物活性粉末可改善混凝土产品的力学性能和耐久性能，本方案可以实现建筑固体垃圾有效的资源化回收利用。
