Identify the amount of pressure required to prevent a soil sample from expanding when saturated.
Carefully trim an undisturbed or compacted soil sample into the consolidometer ring. Take initial measurements of weight, height, diameter, and moisture content.
The standard has critical practical applications in geotechnical engineering: astm d454621 pdf
Designing retaining walls, basement slabs, and deep foundations that must resist lifting forces. 4. Laboratory Apparatus and Setup
Platforms like ANSI, IHS Markit, or Techstreet. Identify the amount of pressure required to prevent
The results are used to calculate the percentage of swell or collapse:
The standard explicitly excludes saturated soils, as the swelling or collapse mechanisms in saturated conditions are fundamentally different. The results are used to calculate the percentage
The 2021 edition replaced the previous ASTM D4546-14 standard. While it maintains the core procedures, it includes minor technical edits and updated references to ensure consistency with modern geotechnical practices. Three Methods of Testing
