Maturity Method vs field cured cylinders
Maturity Method vs field cured cylinders
(OP)
we have a post tensioned parking garage under construction. The testing agent has requested to use the Maturity Method (ASTM C1074) for all concrete strength testing, instead of field cured cylinders.
With Maturity Method, probes were placed at multiple location at the slab prior to pour. After pour, they come with a digital reader to read the concrete strength of the slab at the probe location.
The first pour has succesfull reached the concrete strength with both the Maturity Method and the field cured cylinder test.
Based on this, the testing agent has requested to abandon field cured cylinder testing.
I have no experience in Maturity Method, therefore I am feeling uncomfortable about not doing any conventional cured cylinder testing.
Please, if you have any experience with this, either bad or good, i would appreciate if you could share with me.
Again, please shed some lights on this matter, I would really appreciate that.

Note section 5 where it suggests a limitation on this use and that it "needs to be supplemented by other indications of the potential strength of the concrete mixture." ....section 5.3(3)
I've never heard of using this on a construction project. Only perhaps in a lab for research.

Is the contractor batching the concrete themselves? i would think the concrete company would act like their concrete was perfect if lab-cured cylinders aren't cast and a problem comes up.
i can't think of any alternate tests that don't involve compressing a sample that can stand alone for acceptance testing (and concrete beam testing for pavements). All the other ones, in my experience, are supplemental.

We didnot feel confortable enough to use maturity to determine when to post-tension our structure, but I would be happy to hear from anybody with more experience in the matter.

Taro - thanks for your info. that makes me feel comfortable about the accuracy of the test.
For the rest of you all - Again - thanks!
