Manufactured Aggregate an overview ScienceDirect Topics

The manufacturing process of this aggregate involves agglomeration in a slightly moist environment on an inclined rotating pan. The resulting pellets (10–14 mm in diameter) are then dried and subsequently fed into a rotary kiln or grate furnace, at temperatures between 1100°C and 1200°C, at which a degree of bloating occurs, resulting in a

Construction aggregate

The largest-volume of recycled material used as construction aggregate is blast furnace and steel furnace slag. Blast furnace slag is either air-cooled (slow cooling in the open) or granulated (formed by quenching molten slag in water to form sand-sized glass-like particles). If the granulated blast furnace slag accesses free lime during hydration, it develops strong hydraulic cementitious properties and can partly substitute for portland cement in concrete. Steel furnace slag is also air-cooled. In 2006, according to the USGS, ai
