Importance of swelling index test of soil
Witryna5 maj 2024 · The swelling potential of expansive soils is a key parameter for evaluating the expansion behavior, which is commonly directly or indirectly determined by laboratory tests. Plasticity Index (PI) has been used as a swelling potential indicator for a long time. Seed et al. [ 9] proposed the following empirical relationship: WitrynaSoil compaction is an aspect that is studied and researched by geotechnical engineers [].If we narrow down our focus to arable soil harnessed by the global agricultural …

WitrynaHoltz and Gibbs (1956) developed a simple test called free swell test for the determination of swell potential of a soil. The test is performed by pouring 10cm. 3. of soil passing 425µm sieve into a graduated cylinder glass jar of 100ml capacity filled with wa-ter. The swollen volume of the soil is observed after 24 hours.
