I can relate to the first photo in the article. Not that I have much knowledge about the pixie dust, but back over 30 years ago I suggested wood in some form or compound would be useful in concrete. This was in our small Forest Products Lab at our University. Come to find out the idea was not new even back then. I believe our textbook was something similar to the Wood Handbook, but not the same. It wasn't actually a required text because much of the course was forest products in use not until a later course did we get wood technology looking at properties of wood, identification and cell walls and such. We used the Text Book of Wood Technology. Much of the data came out of the WI Forest Products Lab. A pioneering facility for sure.
