Researchers pour environmentally friendly recycled cement

University of Sydney researchers have successfully poured sustainable cement pavement made from fly ash and recycled waste, such as ground glass and carbon dioxide.

The researchers worked alongside Delta Electricity, recycling company IQ Renew and construction materials and industrial minerals supplier Morgan Ash: an Adbri Company, to develop the technology.

Concrete production is an energy intensive process that involves dredging sand and aggregates, which contributes to erosion and environmental degradation.

The trial cement has saved 752 kilograms of sand from being dredged and 327 kilograms of carbon dioxide from being emitted.
