Co-utilization of waste glass cullet and glass powder in precast concrete products
Graphical abstract Display Omitted
Highlights An eco-friendly concrete product was developed by using waste glass. Waste glass was employed as both aggregates and binder in the eco-blocks. Combined use of GC and GP in blocks reduced water absorption and drying shrinkage. The addition of GP could successfully address the ASR risk triggered by GC. The glass-based block seems to be a promising outlet for recycling of waste glass.
Abstract This study aimed at developing an eco-friendly precast concrete product by enhancing the application of waste glass. The waste glass was utilized as both fine aggregates and a partial binder in the form of glass powder (GP) in the paving blocks. The results showed that the strength was constant despite increasing amount of glass cullet (GC) was used in the paving blocks. The combined use of GC and fine GP was beneficial in reducing the water absorption and drying shrinkage of the paving blocks within permissible limits. Moreover, the addition of GP could successfully address the concern of ASR expansion resulting from GC.
