Moisture Content

2000-3-30  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.

If soil aggregates are wetted slowly at atmospheric pres-sure or quickly under a vacuum, the bonding is still sufficiently strong to hold most of the primary particles together in aggregates. If dry aggregates are wetted quickly at atmospheric pressure, much more disintegration and slaking occur (Panabokke Quirk, 1957).
