WebSoils with high shrink-swell capacity, such as vertisols, recover quickly from compaction where moisture conditions are variable (dry spells shrink the soil, causing it to crack). But clays such as kaolinite , which do not crack … WebThat’s why every construction company needs to have high-quality shrink-swell testing equipment to analyze the swell potential of soil. Looking for a reliable swell testing apparatus? Look no further than Forney’s swell and consolidation machine for two-inch samples. This machine comes as part of a kit that includes a broad selection of ...

WebHigh shrink-swell potential and cracks that are 1.3 to 10 cm (1/2 to 4 in) wide at 30 cm (12 in) depths during dry periods. ADDITIONAL DATA: E. H. Templin, I. C. Mowery, and G. W. Kunze, Houston Black clay the Type Grumusol: Soil Science Society of American Proceedings, Vol. 20, No.1, January 1956. SSIR-30, S53TX-70-1, S54TX-14-90. Due to the physical and chemical properties of some clays (such as the Lias Group) large swelling occurs when water is absorbed. Conversely when the water dries up these clays contract (shrink). The presence of these clay minerals is what allows soils to have the capacity to shrink and swell. Some of these clay … See more The shrink–swell capacity of soils refers to the extent certain clay minerals will expand when wet and retract when dry. Soil with a high shrink–swell capacity is problematic and is known as shrink–swell soil, or See more Clay groups with a high shrink–swell capacity tend to damage crops during dry spells, as the soil contracts, by pulling roots apart. Soils with shrink-swell capacity can cause engineering … See more Many methods may be employed to mitigate or prevent the damage caused by expansive soils. When it comes to foundations, one solution is to extend building foundations to a depth where they are below the zone of water content fluctuation. This … See more Property owners and prospective buyers may check for expansive soils by consulting a soil survey, many of which are created and maintained by the United States Department of Agriculture-Natural Resource Conservation Service (USDA-NRCS).
