Nanometer material co-doped fiber reinforced cement-based material and preparation method thereof
The invention relates to a nano-material co-doped fiber reinforced cement-based material and a preparation method thereof. The composite material mainly comprises a cementing material, multi-walled carbon nanotubes, standard sand, a water reducing agent, water, spandex fibers, mulberry fibers and a surfactant. Wherein the cementing material comprises cement and fly ash; the mixing amount of the multi-walled carbon nanotubes is 0.1%-0.15% of the mass of the cementing material, the mixing amount of the spandex fibers is 0.2%-0.3% of the volume of a formed test piece, the mixing amount of the mulberry fibers is 0.1%-0.2% of the volume of the formed test piece, and the mass ratio of the water to the cementing material is 0.42-0.44. The strength, toughness and durability of the cement-based composite material are improved, the improvement of the microstructure by the nano material and the improvement of the toughness by the fiber are combined, and the cement-based composite material not only has relatively high toughness, but also shows more excellent performance in the aspects of mechanics and durability; the production process is pollution-free, the price is low, the preparation process is simple, and good economic benefits are achieved.
本申请涉及一种纳米材料复掺纤维增强水泥基材料及其制备方法，该复合材料主要包括胶凝材料、多壁碳纳米管、标准砂、减水剂、水、氨纶纤维、桑皮纤维、表面活性剂；其中，胶凝材料包含水泥和粉煤灰；多壁碳纳米管的掺量为胶凝材料质量的0.1%～0.15%，氨纶纤维掺量为成型试件体积的0.2%～0.3%，桑皮纤维掺量为成型试件体积的0.1%～0.2%，水与胶凝材料的质量比为0.42～0.44。本申请提高了水泥基复合材料的强度、韧性和耐久性，通过纳米材料对微观结构的改善和纤维对韧性的提升相结合，水泥基复合材料不仅具有较高韧性，同时在力学方面和耐久性方面表现出更加优异的性能，生产过程无污染且价格低廉且制备工艺简单，具有良好的经济效益。
