Bulk density and free space between aggregates have a great impact on the concrete strength, durability and cement consumption. Bulk density, in addition to lithological properties, is also influenced by the environment in which aggregates accumulate. In order to investigate this subject, aggregate accumulated in three environments (talus, fan and river) in Deira were evaluated. The upstream catchments of these environments are similar in lithology and consist of Asmari thick formation. The results of experiments on different samples show that the aggregate bulk density increases in talus, alluvial fan and river environments, respectively. The bulk density is affected by area and main channel length of the catchments in alluvial fan environment, and it increases as the length of main channel and area of catchments increase.
