[TowerTalk] concrete forms

Don't even think about putting any stress on it for at least a week,
preferably a fortnight. Further if you get very warm wx like I had last year
( yes in GW!), cover with polythene to prevent rapid drying. I think in
principle that separate pourings are not a good idea, as you will get
"layering" Doing it in one go IS possible, but is really not a one man job.
See if you can get a bunch of local boyos to give a hand!

Hi Guys
Over here in the UK, I am about to "plant" 4 towers, and pour C35 Grade
Concrete in the bases. Anyone know what is the setting time for this stuff,
and can it poured in one or two lots ? Getting this amount of concrete onto
the site is not easy. I live up a mountain, with access limited to 4 Wheel
Drive vehicles, and certainly a Truck will be near impossible to get on
site, let alone a Ready Mix Concrete one ! So I may have to mix on site, and
pour in batches.

Comments ?

My son works for a local concrete company and pours thousands of
yards of concrete each week. They do one of two things:

Use disposable forms
Impregnate wood forms with a 50/50 mix of diesel fuel and hydraulic oil

He said they have tried some of the other products but they aren't
worth the cost.

He said to pour w/o forms on the earth as that will give you greatest
strength.
