Production and Uses of Crushed Rock Aggregates: An …
In general, aggregates should be hard and tough enough to resist crushing, degradation and disintegration from any associated activities. About 52% of all construction aggregate is crushed stone, while 48% of the remaining is sand and gravel (AASHTO, 2001). A mineral aggregate is used to denote a rock product as aggregate.

THE ROLE OF AGGREGATES AND SANDS IN THE …
A good concrete aggregate must be clean, chemically inert, and durable and roughly cubic in shape after crushing and of a size grade suitable to make concrete of desired physical qualities. Natural sand consists of loose grains which are commonly the result of the chemical weathering and/or physical breakdown of rocks.
Making Concrete Pumpable| Concrete Construction Magazine
Ruttura says the ideal is to "have at least 270 pounds of water per cubic yard, although we can pump it with down to about 230 pounds with a well-blended aggregate.". A wide array of factors can impact concrete pumpability such as the dimension, shape, gradation, and volume of aggregates and fibers.
Ultimate Guide to Coarse Aggregate in Concrete Construction
This range indicates that the coarse aggregate has a density between 2.4 and 2.9 times that of water. As a result, the thickness of the aggregate itself, expressed in units of mass per unit volume, can be calculated by multiplying the specific gravity by the density of water. The moisture content of coarse aggregate, also known as the quantity ...
