[AT] another new shop

[Larry D. Goss]

The next time any of you travel through a construction zone where they
are pouring a continuous divider wall on an Interstate highway, notice
the process.  The form isn't more than eight or ten feet long, and they
move it along as they pour -- within minutes of when it came out of the
truck.  City street departments do the same thing with poured curbing.
I grew up with the concept of letting concrete set for at least 24 hours
before removing the forms, but that's obviously an old-fashioned idea
nowadays.

first if you took  the forms off while the truck was still there.....how
did
you pick up the  mess......cause it would not stand upright that soon

Agreed that cured in the air is  best

Frank I don't know how wet your pour your concrete But I have worked  in
it 
for over 40 years and I alway pull the forms right away not the next day
as i 
don't like to pry them off with a sledge hammer.  I don't know who you
work 
for but I bet its like the stuff we get out here now sloppy wet with no

strength. The dryer the concrete the stronger it will be that's what I
was  taught 
and none of you will ever change my mind on that. I have seen wet
concrete 
poured where it flaked off until there was nothing left. You only get
cracks 
from freezing if water can get into the concrete simple logic.  Also  to
stop 
cracking then besure that you have a solid foundation to put it on. Sand
or or 
small gravel is not enough you need a good rock base start with large
ones  
then add the smaller size up to the top of the base where sand and or
gravel can  
be used.
