Re: Minimum Temperature Reinforcement

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

In this case the Ferrocement would lend itself to a tilt-up type of
application (you could make and rent or lend the forms and the rollers for
compacting the matrix).  The anchorage would have to be grouting in a pocket
with tendons (bars) grouted in corners or wherever warranted.  Anyway, a
thought your imagination and budget are the limits.
