Concrete aggregate testing for ASR potential

Concrete aggregate testing for ASR potential

Concrete aggregate testing for ASR potential

(OP)
Which of the following tests requires using cementitious materials that are proposed for a specific project? Thanks.
ASTM C1260
ASTM C1567
ASTM C1293

RE: Concrete aggregate testing for ASR potential

probably not this one:
ASTM C1206 - 02 Standard Test Method for Plutonium by Iron (II)/Chromium (VI) Amperometric Titration

RE: Concrete aggregate testing for ASR potential

For our bridge projects, we spec C1260-07 (AASHTO T303-04) for standard mixes, or C1567 when fly ash or silica fume is in the mix.

@cvg It is C1260. Thanks for catching that.

@HotRod10 Say Type I cement is specified in the mix, for either test, do you require using cement from same brand/source as that used on the job, or any cement conforming to C150 Type I will do?

RE: Concrete aggregate testing for ASR potential

I don't know what the Materials guys require for the their testing. I just know what is in our general notes. What I posted above is pretty much the extent of it.

RE: Concrete aggregate testing for ASR potential

C1260 or C1567; however, keep in mind that these tests use a relatively high cement content which makes the mortar bars very strong. There are many ASR issues that can be masked by the strong mortar bars. An example is surface pop-outs. This potential might not show in the tests.

RE: Concrete aggregate testing for ASR potential

(OP)
Thanks for the reply. But I am looking for specifics about the tests, i.e., whether cementitious materials used in the tests should be the same source/brand as those to be used for the construction?

RE: Concrete aggregate testing for ASR potential

No. Only the same class or class of cement.

@ Ron, much appreciated.
