  The Environmental Impact of Recycled Concrete

  2012-8-14 · Katz (2003) investigated the compressive strength of concrete which was crushed to serve as a source of aggregate for new concretes. In the investigation it can be noted that as smaller is the crushed aggregate as higher is the water absorption. Coarse aggregates among 9.54 to 25 mm had absorption of 3.3 in 28 days.

  Quarrying Process And Quarry Products

  Rock from the quarry face is fed into the top of the crusher and crushed rock falls out of the bottom of the jaws. The size of the crushed stone which passes through the jaws is partly governed by the gap set at the bottom of the jaws though larger size rocks can pass through if the rock being crushed is slabby or elongate in shape.
