WebApr 7, 2024 · The effects of external stress (σ v) and compaction characteristics in terms of the compaction dry density (ρ d) and compaction moisture content (w 0) on the swelling characteristics of an expansive clay are evaluated in this study.An oedometer that is modified to prevent the consolidation of the specimens under the σ v before wetting was … There are many oedometer tests that are used to measure consolidation properties. The most common type is the incremental loading (IL) test. Tests are carried out on specimens prepared from undisturbed samples. A stiff confining ring with a sharp edge is used to cut a sample of soil directly from a larger block of soil. Excess soil is carefully carved away, leaving a sample with …
