Implementation of concrete aggregate optimization

To account for aggregates with different specific gravities, the procedure optimizes the aggregate blend based on volume, rather than weight. To do this, the total volume of aggregate V agg is converted to an equivalent mass (weight) for use in the optimization process by multiplying V agg by the unit weight of water and a "standard" …

Quarry Process

What is Quarry Process? Dense graded quarry process is an aggregate material that has been crushed and sized. Quarry process is known by a few different names, including: QP, Dense Graded Aggregates (DGA), shoulder stone, item #4, crusher run and DGABC. Quarry process is composed mostly of 1" minus crushed stone and stone dust.
