Density of Coarse Aggregate GharExpert

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. River gravels make the best coarse aggregate.
