For example, mean values of DRY aggregate stability for all sites determined by RS were approximately 14% lower than values determined by WS . For DRY—WS, aggregate stability in 0.02 M CaCl 2 was 66% compared with 55% by DRY—RS in 0.02 M CaCl 2.

Moisture Content

The AD and wet states represent the variable moisture contents that will exist in stockpiled aggregates. The SSD state is the best choice as a reference state for the following reasons: It represents the "equilibrium moisture" state of the aggregate in concrete; that is, the aggregate will neither absorb water nor give up water to the paste.
