Recycled Concrete Aggregate

Nagatakia et al. (2004) reported sulfate soundness losses ranging from 29.1% to 49% for RCA depending on the source, whereas the value was 9.1% and 2.6% for coarse aggregate and fine aggregate, respectively. This study also observed that when subjected to another level of crushing, the performance of RCA improved drastically.

What are the Different Types of Aggregate Crushers?

Gyratory crushers are also used as aggregate crushers. These types of crushers are similar to jaw crushers, but employ a cone shaped hopper with a smaller cone-shaped crushing head that gyrates around the inside of the hopper in an eccentric movement rather than rotating, crushing the source material until the particles are small enough to fall through the opening at the bottom.
