Resin Reinforced Concrete: Exploring Sustainable Building Materials
The utilization of natural resins as additives in concrete has garnered significant attention in recent years due to their potential to enhance the mechanical properties and sustainability of concrete structures. This experimental study investigates the effects of incorporating Acacia gum and Tragacanth gum into concrete mixtures at varying percentages (0.5%, 1.0%, and 1.5%). The study focuses on assessing the compressive strength, split tensile strength of hardened concrete, and the workability of fresh concrete. All tests conducted on the materials adhere to Indian Standards (IS) specifications. The concrete mix design follows the guidelines provided by the Indian Bureau of Standards (IS) and integrates field experience for grade M30 concrete. The materials selected for the concrete mix include Portland Pozzolana cement (PPC), Acacia gum, Tragacanth gum, fine aggregates, coarse aggregates, and water. Various tests are performed on these materials to determine their properties, such as fineness, standard consistency, soundness, specific gravity, and compressive strength. Experimental results reveal that the addition of Acacia gum and Tragacanth gum enhances the compressive strength of concrete by up to 15% at a 1.5% dosage. Similarly, split tensile strength is improved by approximately 10% with the inclusion of 1.0% Acacia gum. Moreover, the workability of fresh concrete is significantly improved, leading to better flow and ease of placement. The grain size distribution analysis of fine and coarse aggregates shows that the materials conform to the required specifications. The specific gravity of fine and coarse aggregates is determined to be 2.6 and 2.8, respectively. Overall, the findings suggest that Acacia gum and Tragacanth gum have the potential to serve as effective additives in concrete production, offering improved mechanical properties and sustainability.
