Abstract

Many studies on alternative binders have been conducted for a long time to reduce the impact of cement manufacturing and CO2 emissions. SCMs (Supplementary Cementitious Materials) are waste materials (such as slag and fly ash) obtained mostly from industry that have the energy to reduce the clinker content of cement. This material's primary disadvantage is its impact on early strength, as well as its longer setting time, with only a small improvement in increasing strength with age. To deal with this problem, a ternary mix of calcined clay and limestone will be the preferred alternative. LC3 concrete's performance in structural applications is examined in this study, as well as the behaviour of the cement's limestone calcined clay, such as mechanical and durability characteristics. This article discusses the difficulties with LC3 concrete as well as the advantages it has over regular Portland cement. Conclusion: LC3 has better alkali-silica reaction resistance, electrical resistivity, and water absorption in capillaries than OPC. This means it will last longer. However, compared to OPC, it exhibits poorer carbonation resistance, reduced workability, and increased shrinkage.
