Re: Minimum Temperature Reinforcement

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Walter;

I'm probable off base but you may want to look into Ferrocement and the
experience various workers there have amassed.  There has been a good amount
of Italian and Mexican (and even some North American!) work I believe and
the ACI (committee 549 - I think) even has a publication on it.  In your
case the value maybe in thinning up the section (i.e.. less mass) with the
same amount of cement and giving it some shape (scary thing shape).
