Recycled glass aggregate concrete panel (50mm, 75mm, 100mm decorative panels)
Decorative precast concrete panels using recycled glass fines as partial sand replacement (up to 10% by mass demonstrated in Australian research). Use requires ATS 3050/AS 2758.1 compliance and ASR mitigation strategies such as supplementary cementitious materials.

Recycled glass aggregate concrete panels are decorative precast panels that use recycled crushed glass as a partial fine-aggregate replacement in the concrete mix. Austroads ATS 3050 defines minimum requirements for recycled crushed glass used as a partial fine aggregate replacement in concrete. In Victoria, a Sustainability Victoria?funded research project demonstrated that unwashed recycled glass fines of up to 10% by mass can replace sand in concrete and meet AS 2758.1, leading to updates in VicRoads Section 703 for general concrete paving.
- Demonstrated feasibility of unwashed glass fines at up to 10% by mass sand replacement in Australian research
- Austroads ATS 3050 provides a specification pathway for recycled crushed glass in concrete
- Supports diversion of glass fines from landfill
