Special concrete containing modified nanofiber material and preparation method thereof
The invention discloses special concrete containing a modified nanofiber material and a preparation method, and relates to the technical field of concrete, and the formula comprises coarse aggregate, fine aggregate, cement, silica fume, water, quartz sand, ground calcium carbonate powder, a water reducing agent, modified fibers, chitosan liquid and ethanol. The basalt nanofiber and the loofah sponge nanofiber are used, and the basalt nanofiber has the characteristics of alkali resistance and high temperature resistance, so that the basalt nanofiber can be used in alkaline and high-temperature environments of concrete easily and can be combined with a concrete matrix easily, the compressive strength and shear strength of the concrete can be improved, the ductility of the concrete is facilitated, and the practicability is high; due to the characteristics of light weight, toughness and developed pore structure of the loofah sponge nanofibers, the slurry can be well combined with the loofah sponge nanofibers, so that the combining capacity of the nanofibers and the concrete is further improved, and the toughness and ductility of the concrete are further improved.
本发明公开了一种含改性纳米纤维材料的特种混凝土及制备方法，涉及混凝土技术领域，配方包括：粗骨料、细骨料、水泥、微硅粉、水、石英砂、重质碳酸钙粉、减水剂、改性纤维、壳聚糖液和乙醇。通过玄武岩纳米纤维和丝瓜络纳米纤维的使用，通过玄武岩纳米纤维耐碱、耐高温的特性，利于在混凝土的碱性和高温环境中使用，易于与混凝土基体结合，可提高混凝土的抗压缩强度、剪切强度，利于混凝土的延性，实用性高，通过丝瓜络纳米纤维体轻、质韧且孔隙结构发达的特性，利于泥浆很好的与丝瓜络纳米纤维结合，进一步提高纳米纤维与混凝土结合能力，进一步提高了混凝土的韧性和延性。
