Abstract
The research extensively explores transforming concrete characteristics through the experimental examination of Aloevera gel and Large Caltrops gel. The primary components utilized in this investigation comprise of premium-grade Portland Pozzolana Cement (43 grade), M-sand, and 20-mm coarse aggregate. Aloevera gel and Large Caltrops gel are added to the concrete compositions in different ratios, ranging from 0% to 6%, all mixed with water. This study emphasizes the critical significance of conducting a thorough assessment of mechanical properties, with a specific focus on compressive strength, split tensile strength, and flexural strength. The primary aim of this study is to ascertain the most effective combination ratio based on the findings and analysis of the data. Aloe vera gel and a caltrops gel concentration of 6% are identified as the most promising formulations without any ambiguity. This research analysis centers on global initiatives aimed at mitigating the environmental impact of the construction sector by analyzing the reduction of chemical admixture consumption as a means to decrease the environmental footprint. The primary objective of this study is to investigate the capacity of concrete to withstand dry shrinkage, its environmental sustainability, water conservation, and cost efficiency.
using careful experiments. Through a meticulous examination of the hydration kinetics, pore structure, and mechanical strengths, our aim is to offer a full comprehension of the manner in which these amalgamated components contribute to the resilience and enduring durability of the material. In addition, the scope of the inquiry goes beyond the confines of the laboratory, as it explores the economic viability and ecological consequences associated with the implementation of self-curing concrete using natural additives in practical construction situations. By providing the results of this experimental endeavor, we expect to provide significant contributions to the wider academic conversation surrounding concrete technology. The objective of this study is to provide valuable insights to industry experts, researchers, and policymakers, facilitating a more comprehensive comprehension of the possible advantages and obstacles linked to the incorporation of natural additives into self-curing concrete systems. Aloe vera gel has been investigated for its potential as a bio-additive in concrete due to its unique properties, including high water retention capacity and viscosity. Research suggests that incorporating aloe vera gel into concrete mixes can improve workability and reduce water demand, resulting in enhanced hydration and strength development of the concrete (Saravanan et al., 2017). Additionally, aloe vera gel contains polysaccharides and other organic compounds that may contribute to the overall performance of concrete (Saravanan et al., 2017)

1.INTRODUCTION Conventional methods of concrete curing frequently require significant amounts of water and time-consuming external interventions, resulting in practical difficulties and environmental considerations. The incorporation of natural chemicals into self-curing concrete offers a potentially fruitful route for innovation in addressing these concerns. The objective of this study is to investigate the potential synergistic effects of self-curing mechanisms and the incorporation of natural additives on the performance, mechanical qualities, and overall sustainability of the material. This work seeks to analyze the complex interactions inside the self-curing concrete matrix that has been enhanced with natural additives,

Large Caltrops, also known as Tribulus terrestris, is a plant commonly found in arid regions. Recent studies have explored its potential as a natural bio-additive in concrete due to its fibrous nature and chemical composition. Large Caltrops fibers possess high tensile strength and can act as reinforcement within the concrete matrix, improving its crack resistance and ductility (Kaur et al., 2020). Moreover, chemical constituents present in Large Caltrops, such as saponins and flavonoids, may also contribute to the hydration process and overall performance of concrete mixes (Kaur et al., 2020).
