不同混合导电掺和料水泥基复合材料压阻特性的实验研究

利用纳米石墨、炭黑等导电掺料制作的水泥基复合材料的压阻特性可进行交通违规监测.本文实验研究了由石墨、炭黑、碳纤维任意两导电掺料组成的复合导电相制作的高导电长方柱水泥基复合材料,在标准车载大小、不同荷载循环周期作用下的压阻特性.实验表明一定车载力作用下,所选配比情况,含石墨和碳纤维混合掺料的水泥基复合材料的压阻特性最好,含石墨和炭黑复合导电相的次之,含炭黑和碳纤维复合导电相压阻特性不明显.

Experimental Research on the Piezoresistive Properties of Cement-based Composites with Different Conductive Admixtures

Conductive cement-based composites with nano-graphite,carbon black have good conductivity and piezoresistive properties,and it can use to achieve traffic monitoring.In this paper,the piezoresistive properties of high conductivity cuboid cement-based composites with any two-phase composed of graphite,carbon black,carbon fiber,under the standard vehicle force with different load cycle are studied.For the selected cases,experimental results show that cement-based composite mixed with graphite and carbon fiber ...
