چکیده
The whole work is divided into preliminary study and main study parts 1 & 2. In the preliminary phase, SCC mixes were prepared with 3%, 6%, 9%, and 12% SC as a partial replacement for cement. Standard 150 mm cubes were tested for compressive strength following BS standards using a 1000 kN capacity UTM. The optimum mix was identified as 9% SC with 3% superplasticizer and a water cement ratio of 0.58. In Main Study Part 1, conventional C30-grade and SC-based SCC blocks (400 × 200 × 200 mm) were tested after 7 and 28 days of curing. Results showed that SCC blocks with SC achieved 15% higher compressive strength than conventional concrete. Main Study Part 2 involved flexural testing of four reinforced beams (1500 × 125 × 200 mm) using conventional steel and glass fiber-reinforced polymer (GFRP) rebars. All the beams are tested using a 500 kN capacity loading frame. SCC-GFRP beams showed 33% lower ultimate load capacity, 48% higher deflection, and 56% lower ductility compared to SCC beams with conventional steel. Additionally, conventional beams exhibited 40% higher stiffness and no brittle failure, unlike the SCC-GFRP beams. Conventional rebar SCC beam exhibited no premature and brittle failure.
