dc.description.abstractThis research focuses on recycling lime sludge as a calcium carbonate (CaCO3) source in producing a low-clinker cementitious binder and other supplementary cementitious materials. The study comprises three main phases. In the first phase, raw lime sludge collected from the textile industry was analyzed for pH, metal content, anions, and microstructure characterization. The second phase involved recycling and blending lime sludge with other materials to create a low-clinker binder. Various physical properties of the blended cement, consistency, setting time, fineness, and soundness, were examined. The third phase concentrated on understanding these cementitious system's hydration mechanisms, strength development, and microstructure evolution. Notably, the study found that incorporating recycled lime sludge into the binder components resulted in desirable physical and chemical properties. The 15% recycled lime sludge blend with 30% calcined clay promotes the ideal hydration reactions necessary to enhance concrete performance. Moreover, it demonstrated the positive influence of recycled lime sludge on cement properties and hydration products. The specimen, consisting of 45% calcined clay, demonstrated the highest compressive strength at 28 days, followed by the C2 specimen, comprising 30% calcined clay and 15% recycled lime sludge. The strength improvement is primarily attributed to the formation of additional hydrated calcium silicate, a key product of hydration that precipitates within the aqueous voids, contributing to developing a more compact structure. ? 2024 Elsevier Ltden_US
