Constant Head Permeameter for 2.5-9in Sample Sizes
ASTM/AASHTO Constant Head Permeameters use the constant head method for the laminar flow of water through granular soils to determine the coefficient of permeability. Models HM-831 to HM-835 come in sizes ranging from 2.5–9.0in (63.5–228.6mm) diameter to accommodate granular soil permeability testing of a wide range of particle top sizes.
Research on the Critical Value of Sand Permeability Particle …
The permeability of sand is an important factor in determining the movement and occurrence of liquids and gases in sand. The current work studied the influence of soil particle size and gradation on permeability by testing the permeability of different sand samples that consist of defined sand particles in certain ratios. The results of a total of 640 sets of …
Effect of water pressure on permeability of foam …
Foam conditioning is a widely adopted technique in earth pressure balance (EPB) shield tunneling for the purpose of reducing sand permeability and preventing water spewing. The permeability of foam-conditioned sands differs from that of natural sands due to the presence of foam bubbles. This study investigated the effect of water pressure on the permeability of foam-conditioned …

Seawater impact on permeability of compacted bentonite–sand …
The impact of seawater (SW) on the permeability of compacted bentonite‒sand mixtures was investigated. The montmorillonite content ranged from 36% to 64%, and the ratio of the amount of extracted Na ions to the cation exchange capacity (Na/CEC) ranged from 0.01 to 0.84 for the six bentonites used in this study. The higher initial Na/CEC of the bentonite …
Digital Absolute Permmeter | Model 42105 | SIMPSON
The absolute determination of permeability is done by measuring the time required for a specific air volume at constant pressure to flow through the specimen or body being tested. The permeability of either a standard 2 in. x 2 in. AFS or 50mm x 50mm metric foundry sand specimen can automatically be measured. COMPONENTS INCLUDED

Permeability of saturated sands, soils and clays
It is shown that the permeability of a water-saturated sand or fine powder can be calculated with considerable accuracy, if the porosity and the specific surface are known. In particular, the Kozeny theory here discussed leads to a very useful relationship between permeability and porosity.

Permeability of lime- and cement-treated clayey soils
The permeability (k) of lime- and cement-treated clayey soils was investigated in the laboratory by flexible-wall permeability tests and oedometer tests. Test results indicate that for the cement-treated soils (with up to 8% cement content by dry weight), the value of k is almost equal to that of untreated soils under identical void ratio (e) conditions, and the k value …
