Re: Water Retaining Concrete

Anyone think heat of hydration could have caused radid curring and there for
cracking?  Thick concrete placement typically require cooling to prevent
cracking.
Case in point, I witnesed the construction of an X-ray facility (10^6 mev)
concrete walls 5ft+ thick 40 ft high liquid CO2 was added to the mixer to cool
the concrete.
