Quality control of recycled concrete aggregates using Laser-Induced Breakdown Spectroscopy

Upcycling End-of-Life (EoL) concrete

The replacement of natural aggregates with recycled aggregates is hampered by the industry’s perception that recycled aggregates are highly variable in quality and that the cost and time-lag to ensure the quality of recycled aggregates for high-end applications is prohibitive. There is a need to cost-effectively measure the quality of recycled aggregates and make this information available online to ensure that it meets the industry’s requirements. There- fore, innovative recycling technologies that can efficiently identify different contaminant materials play a vital role in upcycling End-of-Life (EoL) concrete and implementing a circular economy.
