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.

Crushing strength of concrete rings with a polyurea reinforce ...

2020/07/01 · Maximum crushing strengths of polyurea-coated concrete rings are attained at higher values of deformation of these components, i.e. the coated concrete rings exhibit higher deformability. The polyurea coating system protects concrete rings against their break-up into separate pieces during the crushing strength test.
