In the construction field, Concrete is one of the most essential materials, second only to water. However, the production of cement, a key component of concrete, is a major contributor to global carbon dioxide (CO?) emissions, leading to environmental pollution, global warming, and climate change. Cement manufacturing requires high energy consumption and releases significant CO? due to the chemical transformation of limestone into clinker.In this study, two specific mix design ratios of lime pozzolana concrete, following the relevant Indian Standard (IS) code, were used to develop structural-grade concrete. The concrete specimens were cured using the wet hessian method to enhance hydration and strength development. Mechanical properties, including compressive strength, split tensile strength, and flexural strength, were evaluated at 7, 28, 56, and 91 days. The test results met the strength requirements outlined in the IS code, confirming the feasibility of lime pozzolana concrete as a sustainable alternative to traditional cement-based concrete.Furthermore, statistical analysis was conducted to optimize the two mix proportions and assess the correlation between compressive strength and both split tensile and flexural strength. The results provide valuable insights into the structural performance of lime pozzolana concrete, reinforcing its potential as an environmentally friendly construction material. By offering comparable mechanical properties while reducing cement usage, lime pozzolana concrete presents a viable solution for sustainable construction practices, helping to mitigate the adverse environmental impacts of cement production.
