This research looked into the behaviour of an SCC reinforced concrete (RC) beam with a biaxial geogrid as an extra reinforcement. The use of geogrid in concrete gave geosynthetics a whole new meaning in structural engineering. Geogrids are utilised in asphalt concrete layer stability, confinement, and strengthening, as well as to decrease 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. One control beam (CB) and four geogrid reinforced concrete beams (GB) with variable geogrid layers from one to five are used in the experiment. The two-point stress on these beams was gradually increased until they collapsed. 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 results of the tests show that geogrid can be utilised as a substitute for steel in structural parts
