Examples of Permeability in a sentence

• Permeability shall be tested in a manner approved by the Engineer.

• Permeability is sensitive to changes in the coarse pore fraction and is thus a means of assessing the degree of compaction of concrete.

• Permeability of Concrete ASTM C 1202-97 Bridge Decks One 4”x8” cylinder shall be tested at 28 days using standard moist curing (2 tests per cylinder).

More Definitions of Permeability

Permeability means the rate at which water moves through a unit area of soil, rock, or other material at hydraulic gradient of one.

Permeability means the capacity of an aquifer or confining bed to transmit water. It is a property of the aquifer or confining bed and is independent of the force causing movement.

Permeability means the property of a soil horizon that enables the soil to transmit gases, liquid, or other substances.

Permeability means the rate at which a soil transmits water when saturated.

Permeability means the ease with which fluid can move through a material and is measured by the rate of flow in suitable units.

Permeability means the rate of movement of liquid through the soil.

Permeability means the ease with which a porous material allows water and the solutes contained therein to flow through it. This is usually expressed in units of centimeters per second (cm/sec) and termed hydraulic conductivity. Soils and synthetic liners with a permeability for water of 1 x 10-7 cm/sec or less may be considered impermeable.
