Ultra-high performance concrete containing nano-crystalline cellulose fibers and preparation method of ultra-high performance concrete
The invention relates to the technical field of concrete materials, and mainly discloses ultra-high-performance concrete containing nano-crystalline cellulose fibers, and the following is the application background of the ultra-high-performance concrete. The invention provides ultra-high performance concrete containing nano cellulose fibers and a preparation method of the ultra-high performance concrete. The ultra-high performance concrete is prepared from the following raw materials in parts by weight: 885 parts of cement, 221 parts of silica fume, 135-221 parts of deionized water, 431 parts of coarse quartz sand, 543 parts of fine quartz sand, 0.45-1.77 parts of cellulose fiber blocks, 8-19 parts of a water reducing agent and 1.5 parts of a defoaming agent. According to the preparation method disclosed by the invention, the nano-crystalline cellulose fiber turbid solution with good dispersity is prepared by reasonably using the nano-crystalline cellulose fibers. The turbid liquid is added into the ultra-high performance concrete, so that the strength can be improved, the self-shrinkage can be reduced, and the problem of unstable volume in the construction process is solved. The preparation method is simple, environment-friendly and suitable for large-scale production.
本发明涉及混凝土材料技术领域，主要发明一种含纳米纤维素纤维超高性能混凝土，以下是其应用背景。本发明提出了一种含纳米纤维素纤维超高性能混凝土及其制备方法，包括如下重量份原料：水泥885份、硅灰221份、去离子水135‑221份、粗石英砂431份、细石英砂543份、纤维素纤维块0.45‑1.77份、减水剂8‑19份、消泡剂1.5份。本发明通过合理地使用纳米纤维素纤维，制备出具有良好分散性的纳米纤维素纤维浑浊液。在超高性能混凝土中加入该浑浊液，可以增加强度并减小自收缩，从而解决施工过程中的体积不稳定问题。该制备方法简单、绿色环保，适用于大规模生产。
