摘　　要：测定了炭黑-水泥体系、铁粉-水泥体系及碳纤维-水泥体系的导电性,对炭黑、铁粉和碳纤维作为水泥的导电相材料与水泥的适配性进行了研究.结果表明:碳纤维作为水泥基机敏材料的导电相较合适,它不仅可提高水泥基体的电导率,而且可提高复合材料的力学性能,并用SEM对碳纤维-水泥基复合材料的微观结构进行了分析.The smart cement bassed composites are prepared of carbon black, iron powder and carbon fiber as conduct phase. The research on the conductivity of the carbon black-cement system, iron powder-cement system and carbon fiber-cement system indicated that： as conduct phase compound carbon fiber is the best choice which can increase the conductance radio of the cement at the same time imporve the mechanical properties of the composites. The micro-structures of carbon fiber （CF）-cement composites were characterized by scanning electron microscope （SEM）.
