The structural performance of latex-modified reinforced concrete beams is examined in this work.The latex modification is accomplished by mixing a certain quantity of latex into the concrete mixture.The purpose of this study is to ascertain how latex modification affects the durability and strength of reinforced concrete beams.In order to ascertain the reinforced concrete beams' load deflection response, ultimate load bearing capacity, and deflection characteristics in comparison to the control beams, the study entailed fabricating the beams both with and without latex modification. The beams were then exposed to flexural loading. Furthermore, the latex-modified beams demonstrated improved durability in terms of resistance to water penetration and breaking.The enhanced tensile strength and flexibility of the latex-modified beams are ascribed to the strengthened bond between the reinforcement and the concrete.The results of this investigation show that latex modification has the potential to be a useful technique for improving the structural performance of reinforced concrete beams. Twenty-one distinct mixes were designed using three different latex percentages—5%, 10%, and 15%—as well as mineral admixtures, fly ash, GGBS, and silica fume, with cement replacement levels of 30%, 30%, and 8%, respectively, using mineral admixtures alone or in combination.
