    Alternative lightweight composite facing members for reinforced soils

    Steel reinforced concrete facing members, which are used to fix geosynthetic reinforcements working against tensile forces inside soils and to resist active lateral earth pressures, have certain disadvantages, such as massiveness and corrosion. In addition, the aforementioned conventional panels arenot economical since they frequently require maintenance and repair in terms of long-term stability. In thisstudy, the utility of alternative composite panels is evaluated with the various arrangement and type of fiberreinforcements and a typical foam concrete. Panel tests and three-point bending tests are realized to determine the experimental behavior of steel, carbon fiber (CFRP) and glass fiber reinforced (GFRP) specimens, as well as unreinforced examples. Although CFRP wrapped specimens cannot reach expectedlevels, samples with GFRP present favorable performance as well as being cheaper. Specimens with matGFRP enhance both strength and deformation capacities according to the results of axial and lateraldeformations under diagonal loading condition. In addition, chopped GFRP applied foam concret especimens have more strength in terms of bending test results, but CFRP reinforcements increase the irdisplacement capacity.
