Effect of adding additional carbon fiber on piezoresistive properties of fiber reinforced concrete pavements under impact load

Abstract EN

Multifunctional Cementitious Composite (MCC) characteristics are directlyrelated to the type and dosage of the Electrically Conductive Materials (ECMs)reinforcing the relevant concrete matrices.

This study investigated the electromechanical capacities of fiber reinforced concrete pavement (FRCP) with andwithout the addition of micro scale-carbon fiber (CF).

The impact energy of FRCPunder compacted load was evaluated initially; then, the effects of 0.5% and 1% content by volume of CF on the piezoresistivity capacities of FRCP wereinvestigated under applied impact load.

This type of load is the most common forcecausing long-term rigid pavement deterioration.

Obtained results showed that theuse of a hybrid fiber (micro-scale carbon fiber 0.5% and macro-scale steel fiber1% by volume) enhanced the impact strength (impact energy) due to CF'sresistance to micro-cracks.

The developed FRCP showed good results in terms of A R T I C L E self-sensing under compact load with both 0.5 and 1.0% by volume of CF.
