纳米级碳纤维混凝土材料性能分析

Performance Analysis of Nanometer Carbon Fiber Concrete Materials

如今,随着各种科学技术的发展,尤其是纳米技术在混凝土领域中的应用,使得混凝土材料不断朝着高性能和高功能方向发展,让混凝土具有更加广阔的应用,同时也促进了建筑行业的发展。作为一种新型建筑材料,纳米级碳纤维混凝土逐步被国内外学者研究,试图提高纳米级碳纤维混凝土的应用效果。文章通过实验分析,研究了几种不同配合比纳米级碳纤维的力学性能,主要包含材料的抗弯强度和劈裂强度。实验结果表明,自密实混凝土比普通混凝土具有更好的抗弯强度和劈裂强度;纳米级碳纤维的分散性越好,越有利于混凝土的力学性能;当纳米级碳纤维的掺量为1.5%左右时,纳米级碳纤维自密实混凝土的劈裂强度最大;当纳米级碳纤维的掺入量大约为1%时,纳米级碳纤维自密实混凝土的抗弯性能最好。

Nowadays,with the development of various science and technology,especially the application of nano⁃technology in the concrete field,the concrete materials are constantly developing in the direction of high perfor⁃mance and high function,which makes concrete have a broader application,and also promotes the development of the construction industry.As a new type of building material,nano-scale carbon fiber concrete is gradually being studied by scholars at home and abroad,trying to improve the application effect of nano-scale carbon fiber con⁃crete.Through experimental analysis,the paper studies the mechanical properties of several nano-scale carbon fi⁃bers with different mix ratios,mainly including the bending strength and splitting strength of the material.The ex⁃perimental results show that self-compacting concrete has better flexural strength and splitting strength than ordi⁃nary concrete;the better the dispersion of nano-scale carbon fibers,the better the mechanical properties of con⁃crete;when the content of nanometer carbon fiber is about 1.5%,the splitting strength of nanometer carbon fiber self-compacting concrete is the largest;when the blending amount of nanometer carbon fiber is about 1%,the flex⁃ural performance of nanometer carbon fiber self-compacting concrete is the best.
