| Abstract: |
| The characteristics and principle of conductive coat are expounded in brief.The conductive coat has been applied on concrete test blocks during the compression test,the data shows that the conductive coat is rather sensitive to formation and extension of tiny cracks.The research shows that the conductive coat has definite application for monitoring tiny crack in bridges and tunnels. |
| Key words: conductive coat,monitoring tiny crack of concrete,impact load |
