Coarse Aggregate in general should consist of natural occurring stones (crushed, uncrushed or broken), riverbed single or pit gravel. It should be hard, strong, dense, durable, and clean. It must be free from veins, adherent coatings and injurious amounts of disintegrated pieces, alkali, vegetable matter and other deleterious substances.

Archaeometry is based on the necessary interdisciplinary relationship between diverse branches of the natural and social sciences. This relationship is essential in archaeology, since, from physical materials (objects), scholars have to face questions that go beyond the limits of the tangible and pertain instead to abstract and social concerns.

"Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load" In situations when aggregate value 30 or higher the result may be a mistake and in such cases the "ten percent fines value" should be determined and used instead.

The angular aggregates consist well defined edges formed at the intersection of roughly planar surfaces and these are obtained by crushing the rocks. Angular aggregates result maximum percentage of voids (38-45%) hence gives less workability. They give 10-20% more compressive strength due to development of stronger aggregate-mortar bond.
