crushing technology for reclycle concrete aggregate

Manufactured Sand and Crushed Stones Processing Technology ...

Aggregate is the most exploited material in the world. It is an important component of concrete and asphalt concrete, accounting for 70% of the volume of concrete. It can inhibit the shrinkage and cracking of concrete and enhance the strength of concrete. Aggregates are divided into natural aggregates and artificial aggregates.

Concrete aggregates properties crushed by jaw and impact ...

Jan 01, 2019  The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms are more efficient in removing the cement paste
