Micro-nano cellulose/nano silicon dioxide composite material synergistically reinforced cement soil and preparation method thereof
The invention discloses micro-nano cellulose/nano silicon dioxide composite material synergistically reinforced cement soil and a preparation method thereof. The method comprises the following steps: treating a paper pulp raw material by using a high-concentration pulping technology to prepare a paper pulp fiber raw material suspension, and carrying out mechanical high shearing on the paper pulp fiber raw material suspension to obtain a paper pulp micro-nano cellulose suspension; and mixing the paper pulp micro-nano cellulose suspension with nano silicon dioxide, and further performing mechanical high shear to obtain the micro-nano cellulose/nano silicon dioxide composite material. And sequentially adding cement, soil, water and the micro-nano cellulose/nano silicon dioxide composite material into a stirrer, and uniformly stirring to obtain the micro-nano cellulose/nano silicon dioxide composite material synergistically reinforced cement soil. The preparation process provided by the invention is simple, low in cost and suitable for large-scale production practice of civil engineering. The micro-nano cellulose/nano silicon dioxide composite material prepared by the invention can obviously improve the mechanical property of cement soil.
本发明公开了一种微纳米纤维素/纳米二氧化硅复合材料协同增强水泥土及其制备方法。使用高浓磨浆技术处理纸浆原料制备得到纸浆纤维原料悬浮液，纸浆纤维原料悬浮液经机械高剪切得到纸浆微纳米纤维素悬浮液；纸浆微纳米纤维素悬浮液与纳米二氧化硅混合后进一步使用机械高剪切制得微纳米纤维素/纳米二氧化硅复合材料。将水泥、土、水和微纳米纤维素/纳米二氧化硅复合材料依次加入到搅拌机中搅拌均匀，即获得微纳米纤维素/纳米二氧化硅复合材料协同增强水泥土。本发明提供的制备工艺简单且成本低廉，适用于土木工程大规模生产实践。本发明制备的微纳米纤维素/纳米二氧化硅复合材料能够显著提高水泥土的力学性能。
