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…

Aggregate size and shape vary, too. The size, which can range anywhere from 3/8 inch to 2 inches or more in diameter, largely determines the depth of exposure. Aggregate shape affects the surface pattern and texture. Rounded aggregates provide the best coverage and a smoother surface while angular aggregates add more texture and dimension.
