Abstract: This study presents an experimental investigation on the partial replacement of Ordinary Portland Cement (OPC) with Limestone Calcined Clay Cement (LC3) to develop sustainable and high-performance concrete. The primary objective is to evaluate the mechanical and durability properties of concrete by replacing OPC with varying percentages of LC3. LC3, a blend of calcined clay, limestone, and gypsum, is considered an eco-friendly alternative due to its lower carbon emissions and reduced energy consumption. In this study, concrete mixes are prepared with different replacement levels, and tests such as compressive strength, workability, and durability are conducted. The results indicate that partial replacement of OPC with LC3 enhances strength and durability while maintaining satisfactory workability. This research highlights LC3 as a viable and sustainable alternative in modern construction, promoting eco-friendly practices without compromising structural performance.
