Abstract: abstract:This paper is aimed at evaluating the properties and effectiveness of concretes containing recycled epoxy/glass (EG) particles, which were chopped and grounded waste copper‐clad laminates or printed circuit board scrap. Recycled EG particles are divided into two portions according to their size: a substitutive material for natural fine aggregate and ultra fine filler, according to the particle size of 150 μm. The percentages of EG particles substituted for natural fine aggregate for the control mix were 10, 20, and 30 wt.% by considering suitable workability. Concrete strength can be significantly improved with EG particles due to the filling effect of ultra fine particles. However, as the substitute percentage of EG particles increases, the slump of fresh concrete drops and low workability is observed in the mixes with 30% EG particle even though superplasticizer is applied. Resistivity increases and absorption decreases as the percentage of fine EG particles substituted increases. The weight loss from sulfate immersion test reduces with the use of EG particles. Test results indicate that the proper application of EG particles would effectively modify the pore system, reduce permeability, and inhibit ions penetration in concrete. By considering the saving of land‐fill disposal cost of waste epoxy and glass fiber scraps, enhancement of concrete properties, non‐toxic waste leaching, and raw materials cost reduction, the effective utilization of recycled EG particles in concrete would be successfully achieved.
