【摘要】：利用石墨作为导电相,水泥、细砂作为基体材料,在石墨、水泥和细砂总质量固定不变的前提下,通过调变石墨在整个基体材料中的质量百分含量制备导电水泥复合材料接地模块.考察了不同石墨含量对导电水泥接地模块电阻率、抗压强度、抗折强度及干密度的影响,确定了具有最佳力学性能和电学性能导电水泥接地模块的制备方法.研究结果表明:当石墨含量为50%的导电水泥接地模块于养护箱中养护28 d后,与按其他石墨含量制备的复合材料相比较,具有良好的力学性能和电学性能,电阻率为0.223 3Ω·m,抗压强度为20 MPa,抗折强度为4.7 MPa,干密度为1.73 g·cm-3,为高性能导电水泥复合材料接地模块的制备提供了理论和实验依据.
[Abstract]:When graphite is used as conductive phase, cement and fine sand are used as matrix materials, and the total quality of graphite, cement and fine sand is fixed, The conductive cement composite grounding module was prepared by changing the content of graphite in the whole matrix material. The effects of graphite content on resistivity, compressive strength, flexural strength and dry density of conductive cement earthing module were investigated, and the preparation method of conductive cement earthing module with optimum mechanical and electrical properties was determined. The results show that when the conductive cement grounding module with 50% graphite content is cured in the curing box for 28 days, it has good mechanical and electrical properties compared with the composites prepared according to the graphite content. The resistivity is 0.223 惟 m, the compressive strength is 20 MPa, the flexural strength is 4.7 MPa, the dry density is 1.73 g cm-3, which provides the theoretical and experimental basis for the preparation of high performance conductive cement composite grounding module.
