WHOA - in essence it might be possible for that to work, yes - but:
First consult a PE who is familiar with the limitataions and ratings of
each component, etc.
I have used a piece of t-rod for a pier pin, installed in this manor -
it was very convenient in supportuing that first section... it did not
make the section climbable but it did make it easier to install the
temporary rope guys.
The epoxies are available in larger quantities from bolt houses and
contstruction suppliers specializing in concrete construction. Look for
guys that sell curing checmicals and bonding agents.
