Mechanical Method for Recycling Original State Aggregate

The demolished concretes have ever been considered as homogeneous materials and simply crushed to produce recycled aggregates which can only be used for low strength concretes. In mechanical processes of intergrinding in combination with pre-crushing, the sieve residue in each size fraction varies with grinding time and residue-grinding time curves of most fractions have their inflection

Concrete Shot Blasting vs Concrete Grinding & Floor Prepration

The two most common methods to mechanical prep a concrete surface are grinding and shot blasting. Shot blasting is a method of surface preparation that uses small beads propelled out of a machine at a high speed. The beads are shot out of the machine, striking the floor and are sucked back into the shot blaster to be reused.
