摘　　要：作为石墨混凝土复合材料机敏特性探索,从材料的表观密度、吸水率、抗压强度、体积电阻率等性能、特殊功能(电热、温敏、湿敏、压敏等)方面进行了基础性能研究,研究表明,随石墨掺量增加表观密度、体积电阻率、抗压强度降低,吸水率提高。The graphite/cement composites were prepared.The foundation properties were studied by density test and sop ratio test and resist strength test and volume resistivity test with various contents of graphite.The properties including electric heating,temperature smart,humid smart and press smart were tested also.The result shows that the content of graphite increase the density and sop ratio and resist strength and volume resistivity become elevation.

关 键 词：混凝土 石墨 体积电阻率
