Recycling of Non-metallic Residue from Waste Printed Circuit Boards to Produce Interlocking Concrete Blocks

Jan 05, 2022 | Sawitri Pianchaiyaphum, Suphaphat Kwonpongsagoon, Premrudee Kanchanapiya, and Chakrapan Tuakta

The process of copper recovery from waste printed circuit board has generated large amounts of non-metallic fraction (NMF) residue. In this research, the residue was recycled as a substitute for fine aggregates at 0%, 5%, 10%, 15%, and 20% to produce interlocking concrete blocks. Properties of the interlocking concrete blocks produced in this study, such as density, water absorption, compressive strength, were firstly examined and the selected mixes were further evaluated for the heavy metal leachability....
