RE: Cold Weather and Concrete

[Subject Prev][Subject Next][Thread Prev][Thread Next]
Jon,

All of the provisions are contained in ACI 306R.  Generally when concrete
freezes prior to hydration, it is not worth much.  You can tell by the thud
a hammer gives when you tap it.  It will never set properly, and should be
replaced.  Monitoring the temperature throughout the operation is very
important.
