SpletReactivity index can be obtained using different tests mentioned in AS2870 (2011) such as core shrinkage test, loaded shrinkage test and shrink-swell test. The shrink-swell test (AS1289.7.1.1 2003) is the most appropriate test among them and recommended in the hand book of AS2870 (2011) (Walsh and Cameron 1997). SpletShrink-swell soil, also known as expansive soil, is precisely what it sounds like. It is soil with high wet expansion volume and high shrinkage when dry. This type of soil can cause significant pressure on homes, foundations, roads, …

Published laboratory test results indicate that the Liquid Limit (LL) of such soils is 50-70, and the Plasticity Index (PI) ranges from 25-45 Atterberg Limits tests were performed in our laboratory to help classify and evaluate the expansion

SpletThe shrink-swell test consists of axial swell strain obtained from one dimensional In soil physics, the soil suction is referred to as consolidation test and axial shrinkage strain obtained the potential energy state of … SpletRecently the loaded shrink/swell (S/S) test has gained popularity for the calculation of S/S index (Iss) since it does not require measurements of soil suctions and assumes a simple linear relationship. To test this assumption, a modified linear shrinkage test (MLS) was used to measure strain at various suction “sign posts”.
