Optimising Efficiency of Using Construction and Demolition Waste in Aerated Bricks

OBJECTIVES

Develop an efficient and sustainable way to recycle aerated bricks from construction and demolition waste

Improve crushing and milling methods to reduce energy use and increase recycling efficiency

Create accurate models to optimise how aerated bricks are processed

Test how pre-treatment methods affect the quality of recycled bricks and concrete

Assess whether recycled aerated bricks can successfully replace traditional materials in new brick products

SUMMARY

This research project, led by RMIT in partnership with Shenzhen Yuezhong Green Building Sc-Tech Development Co Ltd, is focused on finding a circular economy solution for construction and demolition waste by recycling aerated concrete (AAC) bricks into new construction materials. Over the past year, strong progress has been made on the first two research goals: improving how AAC bricks are crushed and milled, and developing models to guide this process. Despite challenges like equipment shortages and lab closures, one of the key objectives has already resulted in a completed journal paper. Ongoing lab experiments are helping to finalise testing. The project team has also built connections with industry partners in both Australia and China, and the research has been shared at an international academic conference, helping to expand collaboration and interest in the work.

OPPORTUNITIES

Access to industry and government funding for circular economy innovation

Practical and valuable application in turning building waste into new sustainable products

Strong potential for collaboration with industry
