Lc3 Blends for Sustainable Strength in Concrete

The construction industry is expanding rapidly, with cement serving as a critical binding material. However, the rising demand for cement has raised serious environmental concerns, including raw material depletion and significant CO ₂ emissions, contributing to an increased carbon footprint. As a result, alternative binders have gained interest among researchers, with Limestone Calcined Clay Cement (LC3) emerging as a promising solution. This study presents a comparative evaluation of Ordinary Portland Cement (OPC) and a prepared mix of LC3, focusing on mechanical performance and environmental sustainability. An experimental investigation was conducted to compare the relevant properties of both Ordinary Portland Cement (OPC) and a prepared LC3 mix, aimed at evaluating their structural performance. Results indicate that LC3 achieves structural performance comparable to OPC while significantly reducing CO ₂ emissions. The findings support LC3 as a viable low-carbon alternative in modern construction, offering a sustainable pathway to meet future infrastructure demands without compromising strength or performance.
