With regards to your article (link: https://theconstructor.org/geotechnical/soil-maximum-dry-density-optimum-moisture-content/18426/), what is the reference in standards.
I done check with BS 1377:1990 Part 4 ; but there is no statement saying the range of optimum moisture content for different soil type.
If your author shall share the standards reference, I am glad to hear that and help to improve my knowledge.

The optimum moisture content of soil actually varies and a standard value for silt, clay, and sand is not strictly mentioned in most of the codes. The values mentioned in the article were based on the general laboratory test values based on Indian Standard Tests and Indian soil conditions.
If my knowledge is right, we do mention the average moisture content value within a range.
Thanks for your feedback and query
