Aggregate Testing Standards — EnviroMINE, Inc.
Natural Sand Gravel vs. Crushed Stone Aggregate. Natural sand and crushed stone are both used regularly in construction. The use depends on specification standards and economic considerations. In the production of portland cement concrete alluvial gravel is typically preferred. The rounded particles result in a wet mix that is easier to work with.

Standard Test Method for Bulk Density ("Unit Weight") and ...
This test method covers the determination of bulk density ("unit weight") of aggregate in a compacted or loose condition, and calculated voids between particles in fine, coarse, or mixed aggregates based on the same determination. This test method is applicable to aggregates not exceeding 125 mm [5 in.] in nominal maximum size.
