The coarse aggregates obtained by different crushing mechanisms (jaw and impact crushers) show very similar characteristics in terms of binder content assessed by acid leaching (27.5 and 26.6 wt.%), water absorption (8.76 and 9.75 wt.%) and porosity (18.6 and 20.2 vol.%).Thus, it is not possible to conclude that any of these mechanisms are more efficient in …

The preparation process for coal gangue coarse aggregate and appearance of raw materials are shown in Fig. 1. First, the massive coal gangue was crushed with a sledgehammer and a jaw crusher, and then the coal gangue was manually screened and the coal gangue with 5∼20 mm was used as CCA and the coal gangue with less than 5 mm was used as CCGP.

There are two basic types of jaw crushers: single toggle and double toggle. In the single toggle jaw crusher, an eccentric shaft is on the top of the crusher. Shaft rotation causes, along with the toggle plate, a compressive action. A …

Crusher run is a blended mix of coarse aggregate and fine aggregate. The combination of both crushed stone and stone dust creates a low void content (the amount of space or air between the pieces of rock in a mix) that is valuable in concrete construction for its compaction ability and drainage characteristics.
