chipslip - sawdust vs hemp hurds

For walls on a small building I had originally thought to use hempcrete, but having a lumberyard nearby, sawdust and wood shavings would be easy to obtain, so I'm wondering whether to put the effort into finding a hurd supplier.  

Does anyone have opinion or experience or advice re  wood vs hemp?

I've got books on hempcrete but haven't found as much on wood slip, so pointers to web or print resources would also be most welcome.

I'm attaching photos of the wood products available to me.  

The only advice I have, is to experiment with it.

I had some success with sawdust and clay, which when mixed, dried and fired creates a porous material. However, it was not strong.
From the pictures, the pieces appear to be quite large to me. But that is just my guess and could be completely wrong.
