Abstract: Beam test of carbon fiber reinforced concrete(CFRC) was done. vaviation rule of electric resistance of CFRC bending specimen under different loading conditions was discussed. The results show that the upper electric resistance of CFRC bending specimen decreases and then increases as loading became larger, but lower electric resistance decreases gradually. Under repeated loading, the electric resistance of tensile region concrete increases continually, but that of compressive region concrete firstly decreases and then increases. The residual electric resistance reflects inner damage and its accumulation of CFRC specimen. Under alternative loading, the electric resistance of CFRC increases as loading cycle prolongs, until the specimen is damaged. The variation rule of electric resistance depends on the electric pole mode.

Key words: material experiments, carbon fiber reinforced concrete, drawing-sensibility, resistance
