In recent times, the demand for raw materials in the production of concrete needs good quality and cost-effective alternative materials like fly ash and alccofine. The replacement of raw materials protects the depleting natural resources and reduces CO2 emissions. The fly ash and alccofine are an ultra-fine cementitious material that offers many benefits, especially in Self Compacting Concrete (SCC). This research paper reports several experiments to explore the possibility of alccofine and fly ash as replacement of cement in SCC. In this research paper, SCC mixtures are designed, and the cement is replaced with alccofine (10%) and fly ash (10%, 20%, 30%, and 40%). Several tests are carried out for analyzing the Split Tensile Strength (STS), Compressive Strength (CS) and Flexural Strength (FS) of SCC. The experimental results shows that the CS, STC, and FS of SCC improved with the inclusion of 10% alccofine and 20% fly ash at the curing stages like 7,14, 28, 56 and 90 days. The SCC mix with 10% alccofine and 20% fly ash obtained effective CS of 63.34 MPa, FS of 10.94 MPa and STS of 5.95 MPa, which are higher compared to other concrete mixtures. [ABSTRACT FROM AUTHOR]
