Saturated-surface-dry - Wikipedia

Saturated surface dry (SSD) 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.. The water adsorption by mass (A m)) is defined in terms of …

Effects of Porosity of Dry and Saturated Sandstone on the Energy

May 02, 2019· A SHPB experiment of porous sandstone was conducted to discuss the influencing principle of porosity on the energy dissipation of stress wave across dry and saturated porous sandstones.

dry wsG e = 1 + S = 0 Note that in discussing soils that are saturated it is common to discuss their dry unit weight. This is done because the dry unit weight is simply related to the voids ratio, it is a way of describing the amount of voids. The submerged unit weight, γ´, is sometimes useful when the soil is saturated, and is given by
