| Abstract: | This paper investigates the correlation of conductivity and damage of the graphene intelligent concrete. Under axial load and cyclic load to the specimen,the change of the concrete damage degree can be shown through the change of resistivity. At the same time,through making use of the nonmetal ultrasonic flaw detection instrument to measure the damage degree of the specimens,according to the stress wave theory,the relation between the damage evolution in concrete and variation of ultrasonic velocity is obtained. The damage is compared with resistivity. The cause of resistivity change is explained by tunnel effect theory. Eventually concluding in the correlation of concrete damage and its resistivity. |
