Young's Modulus and Bearing Capacity of Thin Panels Reinforced with Geogrid and Hexagonal Meshes

The study presented here deals with the basic mechanical properties such as Young's modulus and bearing capacity of thin cement composite elements reinforced with welded square geogrid mesh and hexagonal (chicken) mesh subjected to direct flexure. The major parameters investigated in the study are the number and type of mesh layers in terms of effective reinforcement as well as volume fraction of reinforcement and thickness of the cement composite elements. Sixteen elements were cast and tested after 28 days of curing. By analyzing experimental data, equations for estimation of Young's modulus, first crack stress, first crack moment and ultimate moment of the composite have been developed for practical design. Test results show that the Young's modulus and the bearing capacity at first crack and ultimate of cement composite elements are greater for chicken mesh than for the geogrid mesh.
