Ferronickel slag basalt fiber reactive powder concrete and preparation method thereof
The invention belongs to the field of application of building solid waste in high-performance concrete and application of engineering structures, and mainly relates to ferronickel slag basalt fiber reactive powder concrete and a preparation method thereof. The ferronickel slag basalt fiber reactive powder concrete is prepared from the following raw materials in parts by weight: 95 to 125 parts of cement, 48 to 63 parts of superfine fly ash, 20 to 40 parts of silica fume, 15 to 24 parts of basalt fiber, 55 to 72 parts of medium-fine quartz sand, 32 to 42 parts of fine quartz sand, 17 to 25 parts of superfine quartz sand, 69-93 parts of ferronickel slag, 17-27 parts of water and 0.7-3.2 parts of a high-efficiency water reducing agent. The ferronickel slag is used for replacing quartz sand, so that the cost of the reactive powder concrete can be reduced, a series of environmental problems caused by low-grade utilization of the ferronickel slag can be solved, and the method has the significance of energy conservation, emission reduction and environmental protection. The basalt fibers are used for replacing steel fibers, so that the dispersity of the fibers in the reactive powder concrete can be improved, and brittle failure is prevented. The superfine fly ash can relieve the problem of cement shortage and reduce secondary pollution caused by cement production.
本发明属于建筑固废在高性能混凝土应用以及工程结构应用领域，主要是涉及一种镍铁渣玄武岩纤维活性粉末混凝土及制备方法。一种镍铁渣玄武岩纤维活性粉末混凝土，包括以下重量份原料：水泥95~125份，超细粉煤灰48~63份，硅灰20~40份，玄武岩纤维15~24份，中细石英砂55~72份，细石英砂32~42份，特细石英砂17~25份。镍铁渣69‑93份，水17~27份，高效减水剂0.7~3.2份。本发明用镍铁渣替代石英砂不仅能够降低活性粉末混凝土的成本，还能解决镍铁渣低级利用带来的一系列环境问题，具有节能减排和绿色环保的意义。用玄武岩纤维替代钢纤维可以改善活性粉末混凝土中纤维的分散性，防止发生脆性破坏。用超细粉煤灰能缓解水泥短缺问题并减少水泥生产带来的二次污染。
