Anti-freezing water-permeable recycled concrete co-doped with silica fume and nano SiO2 and preparation method of anti-freezing water-permeable recycled concrete
The invention provides silica fume and nano SiO2 co-doped anti-freezing permeable recycled concrete and a preparation method thereof, and belongs to the technical field of building materials. The permeable recycled concrete is prepared from the following raw materials by weight: 180-200 parts of silica fume, 90-110 parts of nano SiO2, 200-390 parts of ordinary Portland cement, 800-1100 parts of natural coarse aggregate, 400-500 parts of recycled coarse aggregate, 3.8-5.8 parts of an additive, and 90-130 parts of water, wherein the raw materials are uniformly mixed and stirred according to a certain sequence to obtain the required concrete. According to the recycled aggregate pervious concrete, the construction waste and the industrial waste residues are used as main raw materials, so the recycled aggregate pervious concrete not only has higher strength and durability, but also has excellent water absorption, water storage, water drainage and water purification capacities. Compared with a traditional pavement, the recycled aggregate pervious concrete applied to pavement of the concrete pavement has excellent drainage, ventilation, sound absorption, noise reduction and other performances.
本发明提供了一种复掺硅灰和纳米SiO2抗冻性透水再生混凝土及其制备方法，属于建筑材料技术领域，所述透水再生混凝土由如下重量份配比的原料制成：硅灰180～200重量份、纳米SiO290～110重量份、普通硅酸盐水泥200～390份、天然粗骨料800～1100份、再生粗骨料400～500份、外加剂3.8～5.8份、水90～130份；各原料按一定顺序混合搅拌均匀后得到所需的混凝土。本发明的再生骨料透水混凝土以建筑垃圾和工业废渣为主要原材料，不仅具有较高的强度和耐久性能，而且具备优良的吸水、蓄水、排水、净水能力。再生骨料透水混凝土在混凝土路面铺设中的应用，与传统的路面相比，具有优良的排水、透气、吸声、降噪等性能。
