Retaining Walls. Layering crushed concrete is also a great way to create a retaining wall and control erosion on slopes or hills in your yard. Different sizes of crushed concrete can function together to help prevent erosion. A layer of smaller, more broken-up crushed concrete as a base will contribute to the stability of the wall.

A jaw crusher is a compression type of crusher. Feed material is reduced by squeezing it between a moving piece of steel and a stationary piece of steel, with the discharge size controlled by the gap setting, ie the space between those two pieces of steel. The tighter the setting, the smaller the output size and the lower the throughput capacity.

Soft aggregates, such as limestone and sandstone, do reduce abrasion resistance and the quality of aggregate is important in concretes in the strength range 20-35 MPa. Bleeding and segregation of concrete after compaction often lead to the formation of 'laitance' on the surface which, if left to harden, would very easily be abraded away.
