Concrete recycled aggregate and preparation method thereof
The invention discloses a concrete recycled aggregate. The particle size of the recycled aggregate is 5mm-20mm, and the bulk density of the recycled aggregate is 800-1200kg/m < 3 >. The brick is prepared from, by weight, 24 kg to 30 kg of cement, 12 kg to 20 kg of mineral powder, 7 kg to 14 kg of fly ash, 2 kg to 6 kg of steel slag, 6 kg to 12 kg of granite, 6 kg to 14 kg of gypsum, 4 kg to 8 kg of broken bricks, such as 3 kg to 6 kg of shale, 2 kg to 6.5 kg of ceramic and 1.5 kg to 3 kg of regenerated glass. According to the invention, more renewable wastes can be fully utilized for processing, resources are effectively saved, the high-strength recycled aggregate with the quality superior to that of the existing concrete aggregate is fired, compared with the traditional gravel aggregate, the strength of the recycled aggregate is greatly improved, and the high-strength recycled aggregate can be crushed and screened to produce aggregates with different particle sizes, so that the production cost is greatly reduced. The method not only realizes resource utilization of solid wastes, but also saves the cost of raw materials, and is more environment-friendly.
本发明公开了一种混凝土再生骨料，所述再生骨料粒径在5mm‑20mm，堆积密度800‑1200kg/m3；按重量kg计，其原料配比如下：原料包括水泥24‑30kg、矿粉12‑20kg、粉煤灰7‑14kg、钢渣2‑6kg、花岗岩6‑12kg、石膏6‑14kg、碎砖4‑8kg、如页岩3‑6kg、陶瓷2‑6.5kg、再生玻璃1.5‑3kg。本发明可充分利用较多可再生废料进行加工，有效节省资源，烧制出质量优于现有混凝土骨料的高强再生骨料，与传统的砂石骨料相比该再生骨料不仅强度上有很大的提高，而且高强再生骨料可通过破碎、筛分生产不同粒径的骨料，不仅实现了固体废弃物的资源化利用，而且节省了原料成本，较为环保。
