Thanks for the reply I figured wood would absorb water but i also figured that sawdust would be simular to papper and that while mixing it in the mixer it would be fine enough to absorb its amount of water there and release it while cureing in the cement like the papper does. afterall papper is basicly wood sawdust compacted and glued together isnt it? i am not sure I have never made papper but this is my thinking anyway. mabe if I pre soke the sawdust for a day befor using it to mix with the cement?
