Abstract - This study has been undertaken to investigate
materials as partial replacements for natural sand and coarse aggregate in concrete, we aim to make a positive impact on the environment and encourage a shift towards more eco-friendly construction practices. This paper is all about connecting the gaps between the old construction material with some new eco-friendly options. We want to make the construction world greener and more responsible.
the determine the performance of concrete with partial replacement of coarse aggregate with broken roof tiles and fine aggregate with bone waste. The broken roof tiles waste was varied from 0% to 50% for coarse aggregate and bone waste was constant at 4% for fine aggregate in M20 mix. Split tensile strength test was conducted to determine the strength of beam. As per the result analysis the maximum strength was obtained at 30% of partial replacement. This project ensures an eco-friendly and cost-efficient nature of the proposed replacement, aiming to sustainable construction practices.
2. EXPERIMENTAL MATERIALS 2.1 Cement (OPC) In the study, ordinary Portland Cement of Ultra tech was used throughout the investigation. The physical and chemical properties of OPC as determined are given in table 1.
Key Words: Bone waste, Broken roof tiles, split tensile strength, eco-friendly, sustainable

Nowadays, in the construction area, concrete is a big deal, second only to water in usage. But, there's an environmental downside. We're in need of additional materials similar to fine and coarse aggregates to enhance our concrete mix. So, here is the plan that let's consider using Broken Roof Tiles and Bone wastes instead of the usual construction materials. It is not just about being unique but it's about being eco-friendly and changing how we look at construction materials. Bones are tough and strong in animals, and provide structural integrity. The bone utilized from animals either after they're slaughtered and cleaned or from animals that died naturally. Bones last a really long time and history proves it. So, for our project, we're turning them into bone wastes. That means subjecting animal bones to high temperatures and pulverizing them to achieve the required gradation. Using bone waste in construction is special because it adds strength, due to its calcium, phosphate and minerals like magnesium and potassium content.
