As concrete technology has evolved, Geopolymer Concrete (GPC) has emerged as an ecologically friendly material compared to Ordinary Portland Cement (OPC) concrete, which has several complex environmental impacts. Without using OPC, which is typically used as a binder, the GPC has been developed. The base constituent material of GPC, like fly ash, is used to produce binder for geopolymer-reinforced concrete as an alternative. In building construction, the most frequently used component of the reinforced concrete element is a beam made by combining OPC concrete and steel reinforcement. This research involves a critical investigation of the bending behavior of control beams made of conventional reinforced concrete (CRC) and geopolymer reinforced concrete (GRC) beams. This critical review intentions to clarify how to differentiate a flexural behavior between GRC and CRC beams. Data from different experimental studies, which are divided into five parameters namely cracks and failure patterns, failure loads, load and deflection relationships, deflections, and ductility, provide the basis for the research. The results of the analytical review support the claim that the flexural behavior of the two beams exhibits similarities, and is quite typical. Therefore, it is possible to analyze and design GRC beams using the theory and standards used by CRC beams.
