Mass Concrete with Post Cooling System
Mass Concrete with Post Cooling System
(OP)
Has anyone out there had personal experience designing a mass concrete pour which required a post concrete placement cooling system.
If so, do you have any tips regarding design or pitfalls to avoid.
I already have found considerable ACI documentation so I am really asking for personal insights.

In Kuwait, they used ice and refrigeration lines very successfully especially during placement in summer time.

You need to be careful that "chilled" water is just 5-10 degree C cooler than ambient, not more. Moreover in design take into account the amount of concrete consumed by these pipes (loss of section) as it may go subtstantial. Also look for any relative settlement in different sections of mass concrete as it may snap your pipes. If this is case, provide a __O__ loop in pipes to take large deflections.
