COMPRESSION-SENSITIVITY AND TEMPRATURE-SENSITIVITY OF CARBON FIBRE REINFORCED CEMENT UNDER LOW STRESSES
小应力下炭纤维增强水泥的压敏性和温敏性

The electric conductivity of carbon fibre reinforced cement(CFRC) was studied,the changement of resistivity under cyclic compressive stresses and constant compressive stresses were measured under low stresses.The result shows that there is interrelation between the resistivity and the compressive stresses.This reflects the structure in cement specimen and its deformational law. The relation between the temprature and compreeion-sensitivity of resistivity was also studied.
