Mechanical Properties Of Recycled Aggregates Concrete

It involves breaking, removing, and crushing existing concrete into a material with a specified size and quality. 1.2.3 Aggregate Characteristics The crushing characteristics of hardened concrete are similar to those of natural rock and are not significantly affected by the grade or quality of the original concrete.

Crushed Stone Aggregates

Crushed stone aggregates are produced by crushing quarried rock, then screening it to sizes appropriate for the intended use. Production of crushed stone has three stages: Primary crushing to break down the stone to a manageable size; secondary and tertiary crushing to render the rocks into sizes specific to their applications; and screening to separate the crushed stone for further processing
