Use of recycled CRT funnel glass as fine aggregate in dry-mixed concrete paving blocks

The results show that the use of up to 100% CRT funnel glass as fine aggregate in concrete paving blocks not only have satisfactory levels in compressive strength (>45 MPa) and ASR expansion (<0.1%), but improved the resistance to water absorption, drying shrinkage and photocatalytic performance for reducing air pollutants. However, the TCLP results reveal that the casting method of producing dry-mixed concrete blocks had a significant influence on lead leaching, and the replacement ratio of the CRT glass should be limited to about 25%.
