description The cold-bonded pelletizing method is often employed in aggregate production since it uses less energy and helps reduce issues with gas emissions, contributing to economic and environmental benefits. In this study, fly ash was chosen as the raw material and used to partially replace cement in manufacturing artificial aggregate. Three types of fibers (polypropylene, polystyrene, and glass fiber) in different volume fractions were used to investigate their effect on the properties of the artificial cold-bonded lightweight aggregate. After the manufacturing process, aggregates were cured with a 28-day water curing. Their specific gravity, water absorption, density, impact value, and crushing value were tested to analyze the properties of the cold-bonded artificial aggregate. Results show that adding various volume fractions of PS, glass, and PP fibers during pelletization caused a more stable generation of aggregates with enhanced mechanical and physical properties.
