Effects of cold weather on concrete compression strength test results
Effects of cold weather on concrete compression strength test results
(OP)
Civil Folks,
I have run into a re-occuring problem of concrete samples not meeting the required 32MPA strength and was wondering what kind of effect collecting the samples for testing in cold weather (-20 - -35C) can have on the test results. Any input is appreciated.

As for the laboratory, if the curing temperature dips (even slightly), strength results are affected adversely.

As to mortar, I used the rule that no freezing should be allowed in the first 24 hours to be acceptable work.
