Steel fiber cement-based composite material based on nanoscale reinforcement and preparation method thereof
The invention provides a steel fiber cement-based composite material based on nanoscale reinforcement and a preparation method thereof, and relates to the technical field of cement-based composite materials. The composite material provided by the invention is prepared from the following components in percentage by mass: 25 to 40 percent of cement, 7.5 to 10.5 percent of silica fume, 35 to 50 percent of river sand, 5 to 7.5 percent of water, 1 to 1.5 percent of water reducing agent, 5 to 9 percent of steel fiber and 0.01 to 0.15 percent of nano cellulose fiber. A small amount of nano cellulose fibers are added into the steel fiber cement-based composite material, a steel fiber-cement matrix interface transition area is subjected to nano-scale improvement in a mode of reinforcing a matrix through the nano-crystalline cellulose fibers, and the mechanical property can be remarkably improved under the condition of low steel fiber mixing amount; the nano-crystalline cellulose fiber has hydrophilicity and can be tightly combined with the cement matrix, so that the mechanical property of the composite material can be improved; and the nano cellulose fiber also has the characteristics of wide material sources and environmental protection.
本发明提供了一种基于纳米尺度加固的钢纤维水泥基复合材料及其制备方法，涉及水泥基复合材料技术领域。本发明提供的复合材料包括以下质量百分含量的组分：水泥25～40％，硅灰7.5～10.5％，河砂35～50％，水5～7.5％，减水剂1～1.5％，钢纤维5～9％，纳米纤维素纤维0.01～0.15％。本发明在钢纤维水泥基复合材料中加入少量纳米纤维素纤维，以纳米纤维素纤维加固基体的方式对钢纤维‑水泥基体界面过渡区进行纳米尺度的改善，可在低钢纤维掺量下实现力学性能显著提升；且纳米纤维素纤维具有亲水性，与水泥基体能紧密结合，更有利于提升复合材料的力学性能；纳米纤维素纤维还具有取材广泛和绿色环保的特点。
