This study investigates the impact of partially replacing cement with Alccofine on the fresh, strength, and durability properties of SCC. Results indicate that a replacement of 30% Alccofine exhibits superior performance in both strength and durability properties.
Self-Compacting Concrete (SCC), a high-performance concrete with exceptional fluidity and cohesiveness, has gained popularity recently. The consolidation qualities and durability demands of this material require the application of Supplemental Cementitious Materials (SCMs). Alccofine is a type of additive material that has the potential to increase SCC characteristics while lowering the environmental effect of Portland cement manufacturing. In light of these facts, this study focused on the fresh, strength, and durability properties of SCC by partially replacing cement with varying percentages of alccofine such as 0%, 10%, 20%, 30%, 40%, 50%, and 60%. The fresh properties are examined using slump flow, T-50, V-funnel, and L-box as per ISO 1920-13. The mechanical and durability properties were investigated, such as compressive strength test, modulus of rupture, Young's modulus of concrete and water absorption, sorptivity, sulphate resistance, and acid resistance, and were compared with conventional SCC. Results indicated that the replacement of 30% alccofine exhibited superior performance in both the strength and durability properties compared to other mixes.
