摘　　要：具有机敏特性的水泥基复合材料日渐成为研究热点。本文研究了掺有碳纤维的混凝土材料在单轴受压和三点弯曲负荷下的电阻相对变化与材料内部损伤间关系 。Study on smart concrete has become the hot research topic.In this paper,the correlation between fractional change in electrical exstance and damage inside carbon fiber reinforced concrete under uniaxial and three point bending load was studied.The results show that good correlation exists between damage and change in resistance,which provides material base for desiging smart concrete on damage of self diagnose.
