Method for preparing lightweight concrete by using gold tailings as aggregate
The invention discloses a method for preparing light concrete by using gold tailings as aggregate. The method is characterized in that building block raw materials comprise the following components in percentage by mass: 50-70% of gold tailings, 10-15% of cement, 10-30% of river sand and 10-15% of water. The ratio of water to materials is 10-15% of water and 85-90% of materials. The method comprises the following steps: (1) adding water into gold ore tailings and river sand according to a ratio, uniformly mixing, placing in a drying oven, drying, and grinding the mixed gold ore tailings into powder; (2) weighing cement and water according to a ratio, and pouring the mixed gold ore tailings, cement and water into a stirrer; and (3) pouring into a mold after stirring, and waiting for natural air drying. And (4) carrying out random sampling detection on the green body, wherein the compressive strength of the green body meets the GB50107-2010 concrete strength inspection and evaluation standard.
本发明公开了一种金矿尾砂作为集料制备轻制混凝土的方法，特征是砌块原料中各组成成分质量百分比为：金矿尾砂50～70％，水泥10～15％，河砂10～30％，水10～15％。水料比为：水10～15％，料85～90％。步骤为：(一)将金矿尾砂和河砂按比例加水掺拌均匀，放置烘箱干燥，将混合后金矿尾砂研磨成粉末状(二)按配比称取水泥、水，将混合后的金矿尾砂、水泥、水浇筑搅拌机内(三)搅拌完成后浇筑模具中，等待自然风干。(四)对坯体进行随机取样检测，坯体抗压强度符合GB50107‑2010混凝土强度检验评定标准。
