Concrete Crushing Two Brothers Contracting, INC.

Prior to any crushing, the materials have to be sized in order to be loaded into the concrete crushing machines. Concrete and other aggregates are usually sized to 2 ft by 2 ft or less. Rebar needs to be cut / sized so as not to tear the crusher belts or bind up the machine. Any debris also needs to be removed.

Concrete Crushing - an overview ScienceDirect Topics

2010-8-7  The desired concrete crushing failures shown in Figs. 1.24 and 1.25 can only be achieved if IC, CDC and PE debonding can be prevented from occurring before the design load to cause concrete crushing. However, this may not always be possible; in which case, it may be necessary to design for either IC or CDC debonding to occur at the design load so that concrete crushing will not occur.
