摘要: Abstract: Conductive concrete containing nano carbon black (NCB) and fibre (CF) to enable the self-diagnosis of strain damage was studied. The effect NCB CF on workability, mechanical properties fractional change in resistance (FCR) fresh hardened analysed. relationship between FCR, initial geometrical neutral axis (IGNA) degree beam established. results showed that FCR IGNA can be described by First Order Exponential Decay function, slope this function reflects sensitivity conductive concrete. Based above mechanics theory, internal is indicated resistance. This self-sensing applied monitoring flexible components.
