Structural Performance of Biaxial Geogrid Reinforced Concrete Slab

In this study, performance comparison for steel and biaxial geogrid reinforced concrete samples is explored. The basic properties of geosynthetics and concrete ingredients were studied. Formulae and derivations of limiting moment, maximum load, and area of geogrid reinforcements for flexural slab were obtained by limit state design methodology. Three types of textile and one biaxial geogrid were individually employed in concrete specimens (cubes, prisms, and slabs). From the results, the geogrid exhibited good performance with the concrete. The flexural behaviour of the steel-reinforced sample is compared with the geogrid reinforced ones. The flexural test of geogrid reinforced flexural members showed satisfactory results. The load-carrying capacity, deflection, and energy absorption of the geogrid reinforced slab, as compared to the steel-reinforced slab, increased by 25, 6.5, and 23%, respectively. The study demonstrated a sustainable reinforcement of concrete that can be a practical solution to corrosion issues experienced in the construction field.
