Explanation: ""Portland cement concrete can be reclaimed during demolition operations and crushed into a coarse granular material that can be used as a substitute for crushed virgin rock. ....to supply recycled concrete aggregate of sufficient quality for many applications"".
Aggregates, which account for 60 to 75 percent of the total volume of concrete, are divided into two distinct categories - fine and coarse. Fine aggregates generally consist of natural sand or crushed stone with most particles passing through a 3/8-inch (9.5-mm) sieve. Coarse aggregates are any particles greater than 0.19 inch (4.75 mm), but generally range between 3/8 and 1.5 inches (9.5 mm to 37.5 mm) in diameter.
Quanto à dimensão, os agregados classificam-se em:
miúdo: o agregado miúdo é a areia natural quartzosa, ou, se artificial, a resultante do britamento de rochas estáveis, de dimensão máxima característica igual ou inferior a 4,8 mm (NBR 7211 – ABNT).
graúdo: o agregado graúdo é o pedregulho natural, ou a pedra britada proveniente do britamento de rochas estáveis, de dimensão máxima característica superior a 4,8 mm (NBR 7211 – ABNT).
