Maximum allowable concrete temperature 1

[76F1Fan]

We have a bridge pile cap that is approximately 10' thick.
We are concerned about the core temperature during curing.
We plan to place the concrete at night and use ice.

What would be recommended as a maximum core temperature and are there other techniques to use to limit the tempature rise?

There's a lot of guidance on mass concrete pours. There are low heat of hydration cements, but even better is use of fly ash. It's cheaper than cement and adds a lot of attractive properties. Ice is OK, but it doesn't last. The small amount of water in concrete is overwhelmed by the heat in the cement, aggregate and sand. And pouring at night helps slightly, but you're talking about heat that builds up over weeks.
Get a copy of ACI 207.1. There's more there than you'll ever want to know.

See the attached document for general advice on mass concrete placement. What is stated may not comply with all specifications... but this is sound advice from a reputable source.

Thank you.
I have an article from the Jan 2002 Concrete International "Controlling Temperatures in Mass Concrete" which provides some guidance.
