The feasibility of the assessment on the repair quality of concrete structure by the electric conductivity of carbon fiber reinforced concrete(CFRC) was researched,according to the change of the electric conductivity of CFRC,the cement quality of the interface between new and old concrete could be assessed,and which was validated by the thermal conductivity of CFRC.

Through the conformation of carbon fiber reinforced concrete(CFRC)smart layer with definite height in concrete structure and real-time monitoring of electrical resistivity variation,the structure real-time loading and the degree of damage could be forecasted.
