INVESTIGATION ON THE STRUCTURAL PERFORMANCE OF LATEX MODIFIED REINFORCED CONCRETE BEAM

This study investigates the structural performance of reinforced concrete beams that have been modified with latex. The latex modification is achieved by adding a specific amount of latex to the concrete mix. The aim of this research is to determine the effect of latex modification on the strength and durability of reinforced concrete beams. The research involved the fabrication of reinforced concrete beams with and without latex modification the beams are subjected to flexural loading to determine their load deflection response, ultimate load carrying capacity and deflection characteristics compared to the control beams. Additionally, the beams with latex modification showed enhanced durability in terms of resistance to cracking and water penetration. The improved performance of the latex modified beams is attributed to the improved bond between the concrete and the reinforcement, resulting in increased tensile strength and ductility. The findings of this study demonstrate the potential of latex modification as an effective method for enhancing the structural performance of reinforced concrete beams. Design of mix for twenty one different mixes had been used with three different latex percentages 5%, 10%, and 15% with the mineral admixtures, Fly ash, GGBS, and silica fume with cement replacement levels of 30%, 30% and 8% respectively with single and double combination of mineral admixtures.
