The ideal concrete rebar spacing for a 4-inch concrete slab depends on the intended use of the slab, the type of load it will support, and local building codes. Generally, for a 4-inch slab, #3 (3/8-inch diameter) or #4 (1/2-inch diameter) rebar is used. Let's examine the benefits and impact on the slab's strength for 12", 18", and 24" rebar ...

The project has no small amount of rebar (think industrial agriculture), but we do have a breaker on an excavator and a Genesis multiprocessing demolition "snip" that will allow us to pre-process the concrete and minimize the amount of rebar that makes it to the magnet to begin with.

Using a Compact Concrete Crusher. Compact concrete crushers offer another option for processing reinforced concrete in order to extract steel rebar. These portable units are designed to convert concrete and a variety of other materials into secondary aggregate that can be used elsewhere on-site or resold to recover costs.

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.

The non-prestressed beam tested under monotonic load failed by bar rupture. Also, the beam prestressed to 40% of the ultimate capacity of the rebar tested under monotonic load failed by the concrete crushing (CC). Moreover, the 20% and 40% prestressed beams at the highest fatigue load levels failed by concrete crushing.

A smaller concrete crushing angle of CRE coated rebar was also observed as a result of the increased frictional resistance. Through chemical observation and nanoindentation test, Allison et al. [17] found that glass–ceramic coating provided a more gradual transformation in composition and mechanical properties. However, very …

When dealing with steel rebars, debonding occurs because of concrete crushing around the ribs, or because of concrete splitting or spalling. The more bond strength increases and bond length shortens, the more the stress increases in concrete in the anchorage zone and therefore the more the concrete crushing, splitting and …

In addition, since the shear failure of reinforced concrete beams is the result of a complex action of various fractures such as diagonal cracks, concrete strut crushing, bond failure between the main rebar and concrete, and shear rebar yielding and fracture, it is difficult to predict their ultimate strength and failure points .
