Basalt fiber modified graphite tailing sand cement mortar and preparation method thereof
The invention relates to basalt fiber modified graphite tailing sand cement mortar and a preparation method thereof, and belongs to the technical field of mortar preparation, graphite tailing sand is used for replacing part of natural sand to prepare the cement mortar, so that the solid waste graphite tailing sand is recycled and ecologically utilized, and the use of non-renewable resources is reduced; the basic mechanical property of the cement mortar is improved; meanwhile, the crack resistance is improved. Basalt fibers are doped into the concrete, so that the compression resistance, the breaking strength and the drying shrinkage performance are remarkably improved. The preparation method comprises the following components in parts by weight: 20-40 parts of cement, 0-30 parts of graphite tailing sand, 20-80 parts of standard sand, 0.1-0.3 part of basalt fiber, 5-20 parts of water and 0.1-0.3 part of a water reducing agent. According to the cement mortar disclosed by the invention, all the components are synergistically matched, so that the prepared cement mortar can have excellent mechanical strength and drying shrinkage performance.
一种玄武岩纤维改性石墨尾矿砂水泥砂浆及其制备方法，本发明属于砂浆制备技术领域，用石墨尾矿砂替代部分天然砂制备水泥砂浆，不仅使固体废弃物石墨尾矿砂得到资源化生态化利用，减少不可再生资源的使用，还使水泥砂浆提高基本力学性能的同时提高抗裂性能。该混凝土掺入玄武岩纤维，抗压、抗折强度和干燥收缩性能均得到显著提高。制备方法包括以下重量份的组分：水泥20‑40份、石墨尾矿砂0‑30份、标准砂20‑80份、玄武岩纤维0.1‑0.3份、水5‑20份、减水剂0.1‑0.3份。本发明通过各组分的协同配合，使得制备得到的水泥砂浆能够具有优异的力学强度和干燥收缩性能。
