Multi-solid-waste asphalt concrete and preparation method thereof
The invention discloses multi-solid-waste asphalt concrete and a preparation method thereof, and belongs to the field of constructional engineering. The multi-solid-waste asphalt concrete comprises the following components in parts by weight: 10 to 15 parts of waste asphalt, 200 to 250 parts of high-silicon iron tailings, 12 to 15 parts of mineral slag, 3 to 5 parts of water, 0.5 to 3 parts of analkaline excitant and 0.3 to 0.5 part of a composite regenerant. The high-silicon iron tailings, mineral slag, waste asphalt, the alkaline activator and the composite regenerant are adopted to producethe multi-solid-waste asphalt concrete. A large amount of industrial waste can be consumed to produce the multi-solid-waste asphalt concrete, so that environmental pollution can be reduced, and wasteis turned into wealth; and the problems of natural limestone raw material supply and the like are effectively solved. In addition, accumulation of a large amount of tailings can be effectively reduced, and meanwhile, the cost is saved. The method is an effective way for realizing high-efficiency utilization of resources, and keeps ecological balance of water, soil and land.
本发明公开了一种多固废沥青混凝土及其制备方法，属于建筑工程领域。一种多固废沥青混凝土，包括以下重量份数的下列组分：废旧沥青10‑15份、高硅型铁尾矿200‑250份、矿渣12‑15份、水3‑5份、碱性激发剂0.5‑3份、复合再生剂0.3‑0.5份。采用高硅型铁尾矿，矿渣，废旧沥青，碱性激发剂，复合再生剂，生产多固废沥青混凝土。能够大量消耗工业废弃物生产多固废沥青混凝土，不仅可以减少环境污染，变废为宝；而且有效地解决天然石灰岩原材料供应等问题。另外，本发明可以有效减少大量尾矿堆积，同时节约成本。是实现高效率利用资源的有效途径，保持水土、土地生态平衡。
