Abstract
A large number of waste printed circuit boards are produced annually, which looms large as a serious threat to our environment. When discarded in a landfill, printed circuit boards (PCB) contain poisonous and dangerous metallic and non-metallic fractions (NMF). This study illustrates the viability of using NMF recycled from waste PCB as one of the constituent materials in the manufacture of building goods like fly ash bricks and paver blocks as a possible route to environmentally friendly construction. The raw materials were combined with NMF in a variety of ratios ranging from 5 to 25%. In comparison to conventional products, NMF-incorporated fly ash bricks and paver blocks shown an improvement in compressive strength. Fly ash bricks made with NMF showed no efflorescence. In comparison to conventional products, NMF-incorporated products were observed to absorb less water. When compared to the control specimens, the NMF blended paver block specimens showed a significant resistance to water penetration.
