Baking-free brick prepared from polyaluminum chloride slag and tailings
The baking-free brick prepared from the polyaluminum chloride slag and the tailings is prepared from the following raw materials in parts by weight: 100 parts of a dry blend and 13-17 parts of distilled water, the dry blend is prepared from the following raw materials in parts by weight: 40 to 60 parts of polyaluminum chloride slag, 30 to 50 parts of tailings and 15 to 25 parts of quick lime. The method realizes resource utilization of the two solid wastes, namely the polyaluminum chloride slag and the tailings, and has the characteristics of low raw material cost, simple preparation process and no toxic by-products. Through the synergistic effect (hydration reaction) of all the raw material components, on one hand, the baking-free brick has excellent mechanical properties (the compressive strength of a finished product can reach 20-35 MPa), and on the other hand, normal-temperature maintenance relatively simple to operate can be selected in the preparation process of the baking-free brick.
利用聚氯化铝渣和尾砂矿制备的免烧砖，其所采用原料及各原料的重量份数如下：干混料100份，蒸馏水13‑17份；干混料中的原料组成及各原料的重量份数如下：聚氯化铝渣40‑60份，尾砂矿30‑50份，生石灰15‑25份。本发明实现了聚氯化铝渣和尾砂矿这两种固废的资源化利用，具有原料成本低，制备工艺简单，无毒副产物的特点。本发明通过各原料组分间的协同作用(水化反应)，一方面使得免烧砖具有优异的力学性能(成品抗压强度可达20‑35MPa)，另一方面使得在其制备工艺中可选用操作相对简单的常温养护。
