[Diy_efi] ever poured a large slab?

[Bill Shaw]

I did a 24x32 floating slab (14 1/2 yards of concrete) for my garage a 
few years back with the help of my brother.  It took about 6 hours after 
the pour to finish up.  We rented bull floats and a power float to 
finish.  One section of the form moved a about 2" so the front edge 
isn't perfectly straight, and water flows off to the side in one bay,  
but all in all it worked out well.  Five years or so and no cracks with 
a 2 story 'cape' type structure on it.  Next time I would start earlier 
(we started after work),  add a little more reinforcement to the form,   
and have a couple more friends.

hth,
