Investigating the properties of ternary-blended self-compacting concrete with fibre

Self-Compacting Concrete (SCC) is the designation for concrete that flows under its own weight. By creating or introducing SCC, the flow ability of ordinary concrete can be enhanced. This study’s primary focus is on the creation of SCC utilizing ternary blends of cementitious additives. Several tests were carried out to assess the SCC’s mechanical, fresh, and durability characteristics. Energy Dispersive X-ray Analysis (EDAX) and Scanning Electron Microscope (SEM) were used to examine micro level characteristics. The mechanical and durability qualities of SCC have been improved by using a ternary blended SCC mix that contains seventy percentage of Ordinary Portland Cement, twenty percentage of Fly Ash, and ten percentage of Silica Fume. The workability of fresh concrete got reduced by increasing the fly ash, silica fume and glass fibre content that can be improved by adding super plasticizer. The strength and durability performance of hardened concrete were increases with increase in fly ash, silica fume and glass fibre in conventional concrete. The glass fiber reinforced SCC mixes with 0.4 and 0.6% of GF have a strong connection with the cement matrix, as shown by SEM pictures. As fiber dosage is increased, peak load of ternary mixed SCC increases significantly.
