crushing. Coarse aggregates smaller than 20 mm were suggested to be eliminated as they may interrupt the grout flow. Neville proposed the use of coarse aggregates of sizes smaller than 38 mm, with the aggregates being gap-graded and of multiple sizes [13]. Later, the minimum size of coarse aggregates of 10 mm was suggested by Orchard [14].

Aggregate crushing generally can be processed in three stages: primary crushing, secondary crushing and tertiary crushing. Each crushing stage produces different particle size according to end products applications. The major equipment in a primary crushing circuit usually includes only a crusher, feeder and conveyor.

Coarse crushed aggregate is commonly used in landscaping designs. All aggregate is divided into two types: fine and coarse. Fine aggregate is broken up into smaller pieces than coarse aggregate. When put through a separator or aggregate washer, coarse crushed aggregate will pass through a 3-inch (7.62-cm) sieve but will not go through a No. 4

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
