WebThus, the term relative density covers a narrower range of possible numerical values than relative compaction, and is therefore considerably more sensitive to small changes in actual dry densities. Relative compaction is an indicator whether the required degree of field compaction has been achieved or not, as per project specifications.

In geotechnical engineering, soil compaction is the process in which stress applied to a soil causes densification as air is displaced from the pores between the soil grains. When stress is applied that causes densification due to water (or other liquid) being displaced from between the soil grains, then consolidation, not compaction, has occurred. Normally, compaction is the result of heavy ma… WebSep 30, 2024 · The compaction factor test determines the workability of fresh concrete or soil in terms of the internal energy required for thoroughly compacting it. In the case of concrete, the complete structural stability relies on the concrete’s strength and quality. Hence, quality must be controlled during the production phase, where cement, sand, and ...
