1-Dimensional Swelling Test
The Gerlink 1-Dimensional Swelling Test is a solution to find out how much the soil expands when exposed to water or moisture. One-dimensional soil swelling tests are commonly used in geotechnical engineering to measure the amount of swelling experienced by the soil when exposed to water. This type of test is usually carried out on soil samples that confined in a horizontal direction and can experience changes in water content due to the opening of the top of the sample.
The sample chamber was closed and the soil was saturated with water. As the moisture content increases, the soil will expand, then the pressure in the room will increase. The pressure is measured periodically to determine the swelling force that occurs.
Soil swelling tests are also often used in conjunction with other tests, such as Atterberg limits and soil classification tests, to gain more complete understanding of soil properties. All of these tests can provide valuable information about the swelling behavior of the soil, which is important for designing structures built on or near expansive soils.
The ASTM code for the one-dimensional soil swelling test is D4546. This standard test method covers the determination of the potential for swelling or one-dimensional settlement of soil.
