CRUSHERS FOR RECYCLING AND ROCK: WHAT TYPE OF CRUSHER …
Is there a great deal of rebar in the material? My favorite (newer) technology is the shredder for concrete, block, and brick. This shredder can also crush asphalt in 100 degree weather which is a huge perk. It also allows for less prep work (by accepting larger material) and is superior when dealing with contaminants like rebar.

Reinforced Concrete Material Properties (Nonlinear)
The reinforced concrete material model is treated as statistically homogeneous with different tensile and compressive behaviors. It follows a "smeared" crack model where cracking and crushing are simulated via degeneration of the elasticity at integration points instead of tracking individual macroscopic cracks.
