摘　　要：为解决某接地工程中要求降阻材料具有低电阻率、同时还要有一定抗压强度特性的难点,在分析了导电混凝土的降阻原理、基本特性(如抗腐蚀性、长效特性)的基础上,制备了石墨导电混凝土。工程实际应用表明,石墨导电混凝土满足降阻材料和结构材料的双重要求,用石墨导电混凝土施工的接地装置的接地电阻不大于0.5 Ω,现场试验28 d抗压强度15.1 MPa,均满足设计指标要求。In order to resolve the difficulty of low resistance and strength of grounding resistance reducing material in a grounding engineering, focusing on analyzing the graphite electrically conductive concrete of resistance reduction principle ,fundamental features such as corrosion resistance and long effective characteristics,and it is prepared. Engineering application show that the graphite electrically conductive concrete satisfy resistance reducing material and structural material of double standards. As the graphite electrically conductive concrete is applied and stereographic earthing mesh is formed, the power-frequency grounding resistance of the grounding devices are less than 0. 5Ω, and 28days compressive strength is 15. 1 MPa, satisfying the requirements of the specifications.
