Cellulose ether-containing low-cost high-performance cement-based material and preparation method thereof
The invention discloses a low-cost and high-performance cement-based material using cellulose ether and a preparation method. The low-cost and high-performance cement-based material is prepared from the following components in parts by mass: 458 to 532 parts of cement, 667 to 824 parts of fly ash, 222 to 301 parts of sand, 287 to 402 parts of water, 8 to 10 parts of high-efficiency water reducing agent, 33 to 45 parts of polyethylene glycol terephthalate (PET) fiber and 1 to 2 parts of cellulose ether. According to the cement-based composite material disclosed by the invention, cellulose ether is doped, so that fibers can be uniformly dispersed in a matrix, the working performance of the cement-based material is improved, the defects that a traditional PET fiber reinforced cement-based material is poor in dispersity, insufficient in working performance and difficult to realize multi-seam cracking are overcome, and the cement-based composite material with low cost and high performance is provided for engineering practice; the material is low in cost, green, environment-friendly and good in performance, and the use scene of a traditional cement-based material can be greatly expanded.
本申请公开了一种使用纤维素醚的低成本高性能水泥基材料及制备方法，按质量份数配比由水泥458~532份、粉煤灰667~824份、砂子222~301份、水287~402份、高效减水剂8~10份、聚对苯二甲酸乙二醇酯（PET）纤维33~45份，纤维素醚1~2份组成。本发明掺入了纤维素醚，能够使得纤维均匀地分散在基体之中，提升水泥基材料的工作性能，弥补传统PET纤维增强水泥基材料分散性差、工作性能不足、难以实现多缝开裂的缺陷，为工程实际提供了一种低成本、高性能的水泥基复合材料；该材料成本低廉，绿色环保，性能良好，能够极大拓展传统水泥基材料的使用场景。
