Method for preparing concrete block by using modified gold tailings as aggregate
The invention discloses a method for preparing a concrete block by using modified gold tailings as aggregate, which is characterized in that the raw materials of the block comprise the following components in percentage by mass: 70-80% of modified gold tailings, 20-30% of cement and 25-30% of water and 70-75% of materials, and the modification steps are as follows: (1) adding water into the gold tailings and superfine slag powder gel material in proportion and uniformly mixing, the preparation method comprises the following steps: (1) preparing modified gold ore tailings, placing the modified gold ore tailings in a drying oven for drying, grinding the modified gold ore tailings into powder, (2) weighing cement and water according to a ratio, and pouring the modified gold ore tailings, the cement and the water into a stirrer, (3) feeding a mold into a constant-temperature curing area for film curing, and (4) putting the mold under natural conditions after demolding. The problem that a large amount of gold ore tailings are accumulated is solved, pollution of the gold ore tailings to the surrounding ecological environment is reduced, waste is treated with waste, waste is turned into wealth, and waste resources are utilized.
本发明公开了一种利用改性金矿尾砂作为集料制备混凝土砌块的方法，特征是砌块原料中各组成成分质量比为：改性金矿尾砂70‑80％，水泥20‑30％，水料比为：水25‑30％，料70‑75％，改性步骤为：(一)将金矿尾砂和矿渣微粉凝胶材料按比例加水掺拌均匀，放置烘箱干燥，将改性金矿尾砂研磨成粉末状，(二)按配比称取水泥、水，将改性金矿尾砂、水泥、水浇筑搅拌机内，(三)将模具送入恒温养护区薄膜养护，(四)脱模后置于自然条件下，本发明主要原料使用大量金矿尾砂作为集料，解决金矿尾砂大量堆积的问题，减少金矿尾砂对周围生态环境的污染，实现以废制废变废为宝，使废弃资源得到利用。
