[Diy_efi] ever poured a large slab?

[Ernest Buckler]

Steve,
Can you pour it in two sections, each less than the 14' screed board width? 
Depends on how far your delivery truck has to travel, but that sounds like 
two loads anyway, right?  So no skin off their nose if you pour twice, a 
week apart.  You could rent the finishing whaddayacallit with rotating flat 
blades - but I'd like a pro to at least coach that part.  BTW, a clever 
friend did his floor recently with in the floor heating using household hot 
water heater and reg. indl. valving, works v. well despite dire warnings 
that such equipment wouldn't stand up to rigors or provide adequate heat. 
No blowing air, just slightest hum from the low-hp pumps (out and in; only 
one needed but he's an overkill kinda guy).  Next he plans to add solar for 
sunny winter days.  He detailed his own system but said there were 
precedents for aspects of it on the home eco news sites.

By large, I mean 25'x45'?  I poured a 10x20 slab last year for a pump
house (had only ever done fence posts previously) and was pleasantly
surprised at how it turned out, but that size can be screeded with a 12'
board, and a hand troweled finish was fine.  I'm building a steel
building workshop this summer and am contemplating pouring this slab
myself.  I'm OK with the forms and the steel, but not sure if I'll be
able to get a good machined finish.  Is this too big a project for a
DIYer and some friends?

thanks,
