Study on Electrical Properties of Carbon Fiber Reinforced Cement Paste with CCCW

Abstract:

In this work, CCCW (cementitious capillary crystalline waterproofing materials) was added in CFRC (carbon fiber reinforced cement paste). Variations of electrical conductivity of CFRC with fiber contents (0.2%~2.0% by the weight of cement) and CCCW (3% by the weight of cement) were studied. The results showed that the resistivity of CFRC containing CCCW versus the concentration of carbon fiber curves had typical features of percolation phenomena. The percolation threshold was 1.2 wt.%. The relationship between resistance and compressive stress was repeatable in CFRC with carbon fiber content of 1.2 wt.%. The resistance decreased in nearly linearity to the compression stress during loading, and increased during unloading.
