Saturated-surface-dry - Wikipedia

Saturated surface dry (SSD [citation needed]) is defined as the condition of an aggregate in which the surfaces of the particles are "dry" (i.e., surface adsorption would no longer take place), but the inter-particle voids are saturated with water. In this condition aggregates will not affect the free water content of a composite material.
