[Cob] straw in cob or concrete?

[Damon Howell]

Good Day everyone,
	This is kind of off the subject of cob but, maybe someone has done  
it anyway. If straw is to cob as rebar is to concrete, why wouldn't  
using straw in concrete work? I have a little concrete work to do  
where I'm going to try that, unless that seems like a bad idea.
