Low-cost high-strength paving stone and preparation method thereof
The invention discloses a low-cost and high-strength paving stone and a preparation method thereof. The paving stone comprises the following raw material components in parts by weight: 30-35 parts of waste residue powder, 120-150 parts of aggregate, 0.2-0.5 part of a water reducing agent, 0.05-0.1 part of a thickening agent, 8-10 parts of fly ash, 25-30 parts of cement and 10-12 parts of water. The waste residue powder is a mixture of furnace bottom slag and water quenching slag, and the aggregate is tailing slag. Compared with the traditional paving stone, the paving stone disclosed by the invention adopts the industrial waste residues as raw materials, so that the industrial waste residues can be fully utilized, the resource waste is reduced, the production cost of the paving stone product disclosed by the scheme can be effectively reduced, and the paving stone disclosed by the scheme has relatively high breaking strength and compressive strength; the problem that waste utilization of traditional tailing slag and furnace bottom slag is difficult is solved.
本发明公开了一种低成本高强度的地铺石及其制备方法，包括以下重量份的各原料组分：30‑35份废渣粉末、120‑150份骨料、0.2‑0.5份减水剂、0.05‑0.1份增稠剂、8‑10份粉煤灰、25‑30份水泥和10‑12份水；所述废渣粉末为炉底渣和水淬渣的混合物，所述骨料为尾矿渣。本发明相比于传统的地铺石，采用工业废渣作为原料，可以充分利用工业废渣，减少资源浪费，还可以有效降低本方案地铺石产品的生产成本，确保本方案地铺石具有较高的抗折强度和抗压强度，解决了传统尾矿渣、炉底渣难以得到废物利用的问题。
