Is this concrete pour only?

Plus 3 degrees and rising is the normal rule. Freezing of concrete is disastrous. Or do they say that the polystyrene is enough insulation to keep the warm concrete warm?

JohnMo Posted January 12, 2022 Share Posted January 12, 2022 Wages - Myself, no wage, the 2nd guy £10 hour, for hours worked. £1500. Durisol is woodcrete, with PIR insulation -6 is from Durisol build manual. Link to comment Share on other sites More sharing options...

Curing concrete gives off heat so they are allowing that this is contained within the blocks. Might even get too hot in summer. 17 minutes ago, JohnMo said: the 2nd guy £10 hour, Is he available?

Bear in mind where most ICF gets used and see what conditions they pump and fill ICF in. If they waited for it to be -6, they'd waste two thirds of a year!! And in the summer it can be +30 Link to comment Share on other sites More sharing options...

And in the summer it can be +30 You don't wait til it's -6, that's the lowest temperature, not seeing why you would have an issue in summer. Quote from manual "The insulating properties of Durisol Wall Forms allow winter construction without additional heating or insulation sources being required. Durisol wall systems have been constructed in temperatures as low as 22 °F (- 6°C) without any complication." 23 minutes ago, saveasteading said: Is he available?

When pouring mass concrete it is sometimes essential to use chilled aggregate, so that the concrete doesn't get too hot when the heat of hydration kicks in.. I don't know at what temperature though. I assume that it would be mentioned if that applied in this case. Link to comment Share on other sites More sharing options...

You miss my point. In some countries they have much colder weather than here and it doesn't stop them pouring. Not sure what North American opinion is on woodcrete.

Adam2 Posted January 12, 2022 Share Posted January 12, 2022 Not sure what your Concrete plant will batch at, mine wouldn't at -6 so that may be more of an issue. Link to comment Share on other sites More sharing options...
