Method for preparing tailing fiber cement mortar from basalt fibers
The invention discloses a method for preparing tailing fiber cement mortar from basalt fibers. The method comprises the following steps: preparing a tailing fiber cement mortar material and construction equipment; the tailing sand and the sand are stirred and mixed at the normal temperature, and a first mixture is obtained; stirring and mixing the first mixture, cement and a polycarboxylate superplasticizer at normal temperature to obtain a second mixture; stirring and mixing the second mixture and basalt fiber at normal temperature to obtain a third mixture; adding water into the third mixture, and uniformly stirring to form a finished product cement mortar; and performing performance detection on the finished mortar sample to ensure that the finished mortar sample meets the building requirements. A proper amount of basalt fibers playing a bridging role are doped outside the tailing cement mortar, so that the strength, toughness and crack resistance of the tailing cement mortar are improved, the problem of cracking caused by volume expansion of a tailing cement mortar test piece due to a relatively large mixing proportion of the tailing sand is avoided, and the construction cost is reduced while the building requirements are met. The large-scale use of the tailing sand in the cement mortar is realized.
本发明公开了一种利用玄武岩纤维制备尾砂纤维水泥砂浆的方法，包括：准备尾砂纤维水泥砂浆材料及施工设备；将尾矿砂和砂子在常温下搅拌混合，得到第一混合料；将第一混合料、水泥及聚羧酸减水剂在常温下搅拌混合，得到第二混合料；将第二混合料及玄武岩纤维在常温下搅拌混合，得到第三混合料；在第三混合料中加入水搅拌均匀，形成成品水泥砂浆；对成品砂浆样品进行性能检测，以确保其符合建筑要求。通过在尾砂水泥砂浆外掺适量起桥接作用的玄武岩纤维，提升了尾砂水泥砂浆的强度、韧性和抗裂性，避免了尾矿砂掺量比例较大导致尾砂水泥砂浆试件体积膨胀产生裂纹进而产生开裂的问题，在符合建筑要求的同时，实现了尾矿砂在水泥砂浆中的大量使用。
