Some awkward questions about density
Conference Proceeding
Ridley-Ellis, D., & Cramer, M. (2020)
Some awkward questions about density. In Timber 2020 Conference Proceedings. , (99-110
There are several different concepts of wood density, such as specific gravity, basic density, dry density, and oven dry density. These are often confusing, and sometimes poor...
