Not I - haven't heard of it. There's also pumice-crete -

http://www.pumicecrete.com/

...using pumice (highly insulating) aggregate with a small amount of
cement for monolithic pour thick walls. I plan to experiment with
"cinder-crete," since cinder is an abundant local resource in the area of
my property in Hawai'i.

Don't know anything much about woodcement either.

Might they be wood-clay, perhaps with lime? When did what we know as
"cement" (e.g. portland cement) come on the scene?
