Re: Testing Concrete samples

[Subject Prev][Subject Next][Thread Prev][Thread Next]

Alex,

For standard concrete cylinders taken at the job site and sent to a laboratory you were told correct that they should be stored in water up to 3 hours prior to testing.  The details of taking the cylinders, transporting, and curing are contained in ASTM C31.

If you are taking cylinders to determine the "in-place" strength of concrete then you would want to cure the cylinders in a manner as close as possible to the in-place concrete.

Hello.

What is the standard specifications for curing and testing concrete cylinders.

I was told that by one engineer that to immerse the samples in water for 25 days and remove from the water and test it after 28 days.

Thanks for any input.
