High shrinkage soil
WebWith the increase in the water content of the soil its volume remains constant till all its pores fill completely with water and reaches to its shrinkage limit. When the water content of the soil is further increased beyond the shrinkage limit, soil’s volume also begins to increase. WebOn drying the soil decreases its volume by shrinkage, and desiccation cracks appear because of internal stresses in the shrunken and dried soil mass. These cracks are created in pre-existing planes of weakness within soil clods. As a result of shrinkage, soil decreases its height by subsidence.

WebAug 26, 2024 · Expansive clay soils are high shrinkage soils that have low bearing capacity. So an effort is needed to reduce the nature of its swelling. One effort that can be done is the method of soil stabilization, where the soil is mixed with materials that can reduce soil swelling and increase the shear strength of the soil.
Web10 and 12, respectively. At the addition of 6% lime, the natural soil had a reduction in shrinkage to 9%, while soil A’s LS was reduced to 8, soil B’s to 6% and soil C’s to 7%. This indicates that the organic portion of the soils had more improvement in shrinkage, most likely because of the effects of lime on the organics. dark brown replacement windowsFine-grained, clay-rich soils can absorb large quantities of water after rainfall, becoming sticky and heavy.
