This paper illustrates the behaviour of reinforced concrete (RC) beam with biaxial geogrid as an additional reinforcement. The use of geogrid in concrete setup a new dimension for employing a geosynthetics in structural engineering. Geogrids are being used in stabilization, confinement and reinforcement of asphalt concrete layer, further to reduce reflective cracking in pavement applications. The purpose of examining the behaviour of geogrids in structural members gives opportunity to observe benefit and feasibility of using geogrid in thin concrete layers. The experimental investigation consists of one control beams (CB) and five geogrid reinforced concrete beams (GB) with varying geogrid layer from one to five. These beams were subjected to gradually increased two-point load until collapse occurred. The first crack load, ultimate load carrying capacity and behaviour was observed till collapse occurred. The behavior and flexural strength of these geogrid beams were compared with that of a control beam that had the steel reinforcements alone. The test result indicates that geogrid can be used as an alternative material for steel in structural members.
