Assessing the Adequacy of Concrete Mixes Utilizing PCB Powders

摘要: Solid waste management is becoming a sustainability issue in highly industrialized societies. Recycling or reuse of solid desirable to reduce the adverse impact this material. The vast annual production printed circuit board (PCB) Taiwan creates environmental concerns because leaching toxic chemicals into landfills. This study assessed feasibility utilizing resin powder and glass fiber recycled from PCB as partial replacement fine aggregate (natural river sand) concrete. It also established comprehensive test program promote use recycling for reduction. crushed mixed with standard mortar fixed volumetric mix proportion, sand:cement:water = 2.75:1:0.485 was control group fresh hardened properties results specimen showed that addition should be less than 10 %, level 2 %. engineering durability matched those cement group. Because released concretes were found tolerance limit local ordinances, can used mortar, providing an alternative industrial PCB.
