Abstract:Investigates the cracking control effectiveness for flexural cracking of carbon fiber net (CFN) reinforcement, a two-dimensional grid consisting of sets of continuous carbon fibers. Prestressed concrete sheet piles with and without CFN reinforcement were tested in bending and the crack widths were examined. The CFN used in these tests had an element spacing of 20 mm in each direction; each element consisted of three strands each of 18,000 (18K) filaments. The netting was located in the specimens at a concrete cover of 3 mm. Since CFN could be set near the concrete surface and the transverse strands of CFN play an important role in resisting the applied tensile force, the crack widths were controlled effectively. A model for the prediction of crack width in concrete reinforcement with CFN is proposed. Good agreement with the calculated results and the experimental data is obtained.
