swiss schmidt hammer for fire damage to concrete?

[charliealphabravo]

I am looking for a recommendation for a small portable rebound hammer for general use in concrete and masonry field investigations.

I also wonder if it would be useful for testing the integrity of concrete and masonry that has been exposed to fire. Usually I rely mainly on the appearance and sound of the concrete and clues in the fire damage but these are relatively subjective and it would be nice to have a more quantitative test as well.

Any advise is appreciated.

Anyone used this Proceq unit before?

Rebound hammers are fine for a general assessment of consistency. Yes, they can be used for fire damage assessment as they will indicate a "soft" surface...an indicator of carbonation from fire damage.

As long as you don't rely on the rebound hammer for a strength assessment, you can use them for checking area consistency and variation...outside that, they have little use.
