        abstract = {Concrete is a basic material for the construction industry. To fulfil this construction demand, a large amount of concrete is required. Cement, Sand, and coarse aggregate are the basic materials required in construction. The growing demand for cement in concrete causes environmental damage and greenhouse gas emissions. For the production of 1 ton of ordinary Portland cement (OPC), nearly 1 ton of CO2 is released, which accounts for 5-7% of carbon dioxide (CO2) worldwide from manmade sources. This number is undoubtedly rising in the coming decades because developing nations are rapidly building infrastructure to match population expansion. Increasing infrastructural requirements increase the need to produce concrete using conventional materials, which increases the carbon footprint. This study explores the use of supplementary cementitious materials (SCM) from industrial waste materials like Lime sludge and Fly ash used in concrete to minimise CO2 emissions.
Lime sludge is a residual substance that comes from the paper industry, while Fly ash (class F) is a waste material obtained in thermal power plants by the combustion of coal. The current study investigates the effects of adding lime sludge and fly ash to the M20 grade of conventional concrete (0%), as 10% (5% lime sludge + 5% fly ash), 20% ( 10% lime sludge + 10% fly ash), 30% (15% lime sludge + 15% fly ash) and 40% (20% lime sludge + 20% fly ash). Mechanical properties (compressive, split tensile, and flexural strength) were measured at 7 and 28 days. At 10% partial replacement of lime sludge and fly ash, the results performed better than conventional concrete.},
