Lead silica glass waste primarily originates from discarded electronic equipment and cathode-ray tube (CRT) glass, which contains significant amounts of lead and silica. Utilizing this type of waste in cement and concrete serves both environmental and engineering purposes. The lead content, while potentially hazardous, can be stabilized within the cement matrix, preventing leaching into the environment. Simultaneously, the silica content contributes to the pozzolanic reactions in concrete, potentially enhancing the material’s mechanical properties and durability. The incorporation of such waste not only helps in managing hazardous waste but also reduces the need for virgin raw materials in cement production.

Lead Silica Glass Waste

摘要

Lead silica glass waste primarily originates from discarded electronic equipment and cathode-ray tube (CRT) glass, which contains significant amounts of lead and silica. Utilizing this type of waste in cement and concrete serves both environmental and engineering purposes. The lead content, while potentially hazardous, can be stabilized within the cement matrix, preventing leaching into the environment. Simultaneously, the silica content contributes to the pozzolanic reactions in concrete, potentially enhancing the material’s mechanical properties and durability. The incorporation of such waste not only helps in managing hazardous waste but also reduces the need for virgin raw materials in cement production.
