Abstract
This study explored the potential of using EPS waste as a substitute for synthetic resin in particleboard production. The objectives were to assess the impact of various processing parameters, including board density, EPS waste percentage, and pressing temperature, on the properties of the board. For this purpose, lab-scale particleboards were fabricated by combining kelempayan wood particles with EPS waste powders. Subsequently, the physical, mechanical, and thermal stability properties of the board were assessed. The results indicated that the board density, EPS waste percentage, and pressing temperature influenced the physical, mechanical, and thermal stability properties of the board. The bending properties, internal bond (IB) strength, and thickness swelling (TS) of the board exhibited an upward trend with increasing board density. At the same time, the TS decreased while bending properties and IB strength increased with rising EPS waste percentages and pressing temperatures. Notably, the board fabricated with a target density of 0.70 g/cm3, comprising 20 % EPS waste and pressed at 180°C, met the standard requirements for particleboard designated for construction purposes, except the modulus of rupture (MOR), which is slightly lower than the standard requirement. In addition, the thermal stability of the board increased with higher pressing temperatures. Conversely, increasing the density and EPS waste percentage to 40 % appeared to decrease the thermal stability of the board. These findings underscore the significant potential of EPS waste as a binder in particleboard production.
期刊介绍：
Construction and Building Materials offers an international platform for sharing innovative and original research and development in the realm of construction and building materials, along with their practical applications in new projects and repair practices. The journal publishes a diverse array of pioneering research and application papers, detailing laboratory investigations and, to a limited extent, numerical analyses or reports on full-scale projects. Multi-part papers are discouraged.
Additionally, Construction and Building Materials features comprehensive case studies and insightful review articles that contribute to new insights in the field. Our focus is on papers related to construction materials, excluding those on structural engineering, geotechnics, and unbound highway layers. Covered materials and technologies encompass cement, concrete reinforcement, bricks and mortars, additives, corrosion technology, ceramics, timber, steel, polymers, glass fibers, recycled materials, bamboo, rammed earth, non-conventional building materials, bituminous materials, and applications in railway materials.
