Soil Compaction
Soil Compaction
(OP)
I know that soil compacted at 95% does not mean there will be 5% settlement just based on experience. But how do I explain it to someone inexperienced?
Please help me understand it better!
Thanks

RE: Soil Compaction
how to get people to understand things is different for everybody. i suppose i would focus on getting them to understand that the Proctor is just a reference level of compaction that we all just decided on. We could write a new ASTM and call it the Stupid-Proctor. Each lift gets 1 blow per lift for a total of 3 blows. It is pretty easy to imagine that 105% compaction of the Stupid-Proctor will have more settlement than if the soil was compacted to 95% Standard Proctor.... Better-Compacted soils settle less than Worse-Compacted soils, but that doesn't mean we can fill in the blanks for things we haven't tried to learn.
Another concept i've brought up with technicians to keep them on their toes.. Ask them what the moisture content of a pure glass of water is. Usually they'll immediately say 100%. The answer is Infinity %.

RE: Soil Compaction
If the sample volume changes with water content then you normalise with respect to wet mass rather than dry mass. As such, 100 % is correct.
You might come across this in geotechnics/mining if you encounter coal: coal water contents are normalised by wet mass rather than dry mass.
RE: Soil Compaction
i'm sure there must be a standardized test out there for characterizing the amount of water in something that would let a full glass of water be 100%.

What's the plan? Might as well answer him in Latin or Pig Latin.
Even this OG is mystified by all these strange undefined words.
