Challenge and proposed solution

Concrete production in Victoria relies on aggregate and cement sourced from natural and finite sand and rock deposits.

These deposits are declining in viability as there is a shortage of quarry materials and natural sands. Alternative sources of sands and aggregates are urgently required to meet forecasted consumption.

The Office of Projects Victoria (Vic Government), Sustainability Victoria and RMIT University have partnered to response to this demand-supply imbalance in the Victorian infrastructure and waste recovery sector. With the support of SmartCrete CRC, they will investigate and implement new applications of domestic and industrial waste materials in the concrete construction industry. Researchers will develop a green star rating premix concrete using existing household material waste and commercial/industrial material as alternative aggregate. To provide long-term environmental and economic benefits, they will re-qualify waste materials to generate a valuable resource material for the concrete construction industry. Materials such as recycled plastic flakes (HDPE) and fines (PET), rubber fines (LDPE), crusher dust fines, recycled concrete aggregates, and supplementary cementitious materials will be tested.
