hilti question

[delagina]

how do you know which one is preferable to the other, say hit re 500 to hit-ice

thanks,

RE-500 is stronger then HIT-ICE (which is very close to HY-150) but gels and cures much faster, especially in cold weather. If ICE is strong enough use it. It is much more efficient for installing alot of anchors (less time waiting for cure before tightening nuts), especially in the winter. In hot weather I'd rather use HY-150 or RE-500 first, because ICE gels almost to fast.

RE-500 is approved for use in cracked concrete. Read the ESR reports of both before makeing a selection.

I don't think ICE is approved for strength design.

I don't have enough experience with these anchors to comment intelligently. I would contact my Hilti rep and try to find out which anchor is best for the purpose.

HY-150 Max-SD

Just looking through the product data provided by the manufacturers website, it seems to me that the HY-150/ICE epoxies are faster setting then the RE-500. I don't see anywhere in the brochure where it says that HY-150 may be used for overhead applications (if it were your intention to use an epoxied anchor for tensile applications).

Don't be fooled by the manufacturer saying that epoxy has 'high performance under elevated temperatures'. As far as I'm concerned, unless there is a test certificate from an accredited laboratory saying that their product has been tested under the appropriate conditions then the epoxy can not be used where fire resistance is required.

HY-150 is not epoxy, it is an acrylic/methacrylate.
Always adhere to the ICC report, if one is available. Hilti provides these on their website.

Check for the latest info on the website, as I see some recent changes. One is not better than the other, but each will be better for specific uses.

The latest versions seem to be HY 150 MAX and RE 500 SD.

Every kind of chemical anchor is sensitive to installation, even the tolerant ones can fail if installed incorrectly.

Another important consideration is set time. It can vary significantly between them, depending upon ambient temperature. It may not be an issue in many places, but in Texas it can be considering we only have two seasons.

Don't forget to consider hole conditions, as they could dictate which product to use. How will the hole be made? Core drill or regular drill? Is the concrete still green? Will the hole be damp or wet? Will the hole size be correct, or will it be oversized?

All of these things will have an impact on your selection, as each product deals with each condition differently (or doesn't deal with some of them at all.)

Persoanlly, I always use RE500. It deals with all bad conditions, wet holes, oversized holes, etc.. Plus, in my area, it is easier to find as the local supply place stocks it. And I have even been told it is less expensive than the 150. Not sure if that is true though.
