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 appliions; and screening to separate the crushed stone for further .
Crushed aggregates provide major environmental benefits ...
If you don't apply the correct crushing technology, the aggregates will consist of sharp and angular clasts which make the concrete more difficult to work with", says Aarstad. Transporting the material over short distances, and preferably by boat, will result in major reductions in environmentally harmful emissions.
