Webb19 jan. 2024 · Besides, the plasticity index, ranging from 18.7 to 26.1, had an average value of 23.12, which presented poor engineering quality with the state of flow plasticity. Therefore, the silt liquid limit did not meet the requirements for subgrade filling and must be improved before the construction. (2) Chemical properties WebbSoil material with a plasticity index close to 16 percent has the best compaction characteristics. For each soil, there is an optimum moisture content that will permit the soil to be compacted to the maximum degree with the least effort and allow the compacted soil to attain its lowest permeability.
WebbMonitoring data were collected pretreatment, during treatment, and post-treatment, and then interpreted to evaluate the effectiveness of MID for reducing Sr in fine grained, low plasticity silts in the two distinct sites. Webb19 sep. 2024 · IP = 0.73 (WL – 20). The equation of A-line gives value of plasticity index ranges from 0 to 58.4 corresponding to values of liquid limit from 0 to 100%. The plasticity characteristic of fine grained soil based on different liquid limit range is shown below. From the plasticity chart, CL: Clay with low plasticity. ML: Silt with low plasticity.
Webbearthquake. The low plasticity silt from Mississippi River Alluvial will be identified with several index properties tests and static and liquefaction testing. The influence factors of the monotonic shear strength of the silt will be studied, including the OCR, confining pressure, and void ratio.
The plasticity index (PI) is a measure of the plasticity of a soil. The plasticity index is the size of the range of water contents where the soil exhibits plastic properties. The PI is the difference between the liquid limit and the plastic limit (PI = LL-PL). Soils with a high PI tend to be clay, those with a lower PI tend to be silt, and ... Visa mer The Atterberg limits are a basic measure of the critical water contents of a fine-grained soil: its shrinkage limit, plastic limit, and liquid limit.
