Concrete performance is highly dependent on curing efficiency, and inadequate curing often leads to reduced strength, increased permeability, and durability loss. This study explored the feasibility of using natural self-curing materials such as Aloe Vera Gel (AVG) and Jackfruit Seed Powder (JSP) in M25 grade concrete. These materials are selected based on their moisture-retaining and bio-polymeric characteristics, which contribute to internal curing mechanisms. Aloe Vera Gel improves hydration by retaining water within the concrete matrix, while Jackfruit Seed Powder enhances particle bonding and reduces internal voids due to its starch-rich composition. Experimental results indicated improvements in workability, compressive strength, and split tensile strength when compared to conventional concrete. The optimum mix (2.5% AVG + 0.5% JSP) showed approximately 12.9% improvement in workability, 2.07% increase in compressive strength, 2.17% increase in split tensile strength, 6.1% in load-carrying capacity and 7.57% increase in cost compared to conventional concrete. The study concludes that natural admixtures can serve as sustainable alternatives to conventional curing practices while enhancing overall concrete performance.
