Waste Cathode Ray Tube (CRT) glass is categorized as hazardous waste because of its high lead oxide (PbO) content, which contributes to around 25% of the funnel. PbO leaching causes major health and environmental problems since lead levels in mortar containing broken CRT glass (GC) fine aggregate exceed the allowed limit of 5 mg/L. A new recycling technology based on proper melting and annealing has been devised to manufacture spherical CRT funnel glass (GS), which eliminates the possibility of Pb leakage. This study used CRT funnel glass as a substitute for natural aggregates in high-strength concrete (HSC). The study comprised manufacturing concrete mixtures with 0%, 50%, and 100% GS substitutes, as well as 0.5% polypropylene fiber (PPF). The methodology includes slump tests, density tests, compressive strength testing, and Ultrasonic Pulse Velocity (UPV) tests to evaluate workability, density, strength, and quality. The addition of GS increased workability and lowered density while decreasing compressive strength. The study found that CRT specimens constructed using HSC0.5GS had the highest strength of 53.38 MPa, 3.75% higher than HSC0.0GS, and a slump value of 61 mm. HSC0.5GS had its highest density at 2545.23 kg/m3. The UPV results confirmed these findings, with HSC0.5GS having the highest velocity of 4.4 km/s, suggesting greater quality and compaction. Overall, findings show that the ideal mix design, including 50% GS greatly enhances concrete strength and quality, increasing its potential for future applications.
