The engineering carbon fiber deployment in the concrete mix is critical to the success of concrete technology with carbon fiber reinforcement. the change of resistivity to result sensitivity that is affected by the bond between the carbon fiber and concrete matrix itself.
From these preliminary results it is necessary to test and further engineering material about carbon fiber percentage range of 0.5% by weight of cement.
