A Study of the Replacement of Natural Coarse Aggregate …

Despite the spherical and crushed CRT glass being stronger than gravel, the results revealed a reduction in compressive strength of the concrete. However, using a lower water to binder (w/b) ratio and a higher superplasticizer (SP) dosage, it is found to enhance the compressive strength of 60.97 MPa at 28 days that is lower by 13% than the control specimen.

The effects of using cathode ray tube (CRT) glass as coarse …

Even so, the author''s earlier work [] proved that the used of CRT funnel glass in the form of spherical glass (GS) and crushed glass (GC) has pointedly reduced the Pb leaching value. Therefore, it shows that other than conducting a nitric acid treatment, the used of spherically shaped glass and bigger size, ranges from 4.75 to 19 mm could also resolve the Pb leaching issue.

Good Point: Ethical Electronics, Recycling "e-Waste" Blog: …

It is correct that CRT glass can be used as a silica source in a lead smelting furnace but it is wrong to imply that 220 tonnes of lead ore can be entirely displaced by 220 tonnes of CRT glass. Smelter operators keep the silica additions to an absolute minimum as it takes a lot of energy to melt silica and they want to produce as little slag as possible.
