Aggregates cementorgConcrete Crushing an overview ScienceDirect Topics

Natural gravel and sand are usually dug or dredged from a pit river lake or seabed Crushed aggregate is produced by crushing quarry rock boulders cobbles or large size gravel Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases soil cement and in new concreteThe desired concrete crushing failures shown in Figs 124 and 125 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
