Paragraph starter
Research indicates that processed cathode ray tube (CRT) glass can be effectively utilized as a partial aggregate substitute in cementitious materials, offering a sustainable solution for electronic waste management. Studies have shown that incorporating CRT glass at lower percentages (e.g., 10-30%) can result in comparable compression strengths to conventional aggregates, while simultaneously diverting hazardous waste from landfills and reducing the demand for virgin resources.
