Crushed aggregate is produced by crushing quarry rock boulders cobbles or large-sie gravel. Recycled concrete is a viable source of aggregate and has been satisfactorily used in granular subbases soil-cement and in new concrete. After harvesting aggregate is processed crushed screened and washed to obtain proper cleanliness and gradation

The aim of this study is to numerically investigate the influence of particle breakage on the mechanical behavior of granular materials using a discrete element method DEM. To enable particle crushing non-crushable elementary particles are boned together to represents the granular aggregates which can be crushed when the external force exceeds its strength. The flaw of the aggregate was

A loading crushing test of recycled mixed coarse aggregates in the same particle diameter range is carried out and the crushed coarse aggregates are screened manually sorted and weighed to study the crushing characteristics of recycled mixed coarse aggregates. The results show that the effect of reinforcing the strong and discarding the weakx201d exists between two types of recycled

2011-11-10the following conclusions can be made a the angle of repose of the granular systems was influenced by the degree of roughness of the base on which the grains came to rest. The rougher the base was the higher was the angle of repose b the mode of failure of the conical pile of grains was different depending if the base was rough or smooth
