Has anybody used this (or similar product):
http://www.homedepot.com/p/Sika-33-fl-oz.../205671519
I'm doing a section of fence where I'm drilling holes into the lava and setting the T-posts inside and using about a 1/2 cup of concrete per post to cement them in, but this product sets in only 3 minutes.
Experiences? Opinions? Thread hijacks? Any and all appreciated.

Sika Fence Post Mix is a two component, pre-proportioned polyurethane resin. It is mixed in the bag to produce expanding foam for supporting and backfilling fence, mail box, gate and signage posts. Suitable for all types of posts including wood, steel and PVC.

Interesting for sure, but how would you use it since you "mix in the bag" and it sets in 3 minutes and has the coverage of 2, 50lb bags of concrete mix? I am imagining you running from hole to hole, trying to set this into a bunch of posts, before the 3 minutes are up. [

It's used for 4x4 posts.Not sure it would work for your project.
I have used Sika's other products and they are great.
Here is a link with a video :

as someone who has a hard time lifting concrete, love the idea, but always wonder about these new products and how they would work in the rain forest...

I have used Sikaflex Caulking in building homes for years, and have had zero failure, so I trust their product. However, I feel the post epoxy is not really cost effective being twice the price of concrete per hole, as the average post hole takes two bags of post mix concrete, or one bag of Sika product. The other concern is the three minute set time, which to me is extremely short window to apply the product, and if the post moves while it is setting, even more stress on ones mind to correct the problem within that window.
Either way, the company probably feels that their product is ideal in "time savings", as one that is familiar with this use could theoretically set posts on their "three minute set schedule" and complete a fence run in a day, whereas with concrete a fence run takes two days, one to set posts, the other to build the fence to the cured posts. The other advantage they may see is it will work as a great substitute for concrete in an application for fence repair where security, or animal containment is immediately necessary, which is a great product for same.

Not sure if you saw the reviews for this product:

It looks like some people are so happy with it that they indicate the few negative reviews must be written by people who fail to follow package instructions.
Something I like about concrete is I can break it off the pole and reset if needed. I'm not sure if that is possible with this stuff.

This product sent me down the rabbit hole of internet research. I'm drilling holes in rock that are barely bigger than the fence post. It doesn't wiggle around enough to be worrisome in fact some times I need a post driver to get it in. The type of spray foam (Great Stuff) that we're used to might actually be sufficient. They have landscaping and pond/stone varieties I need to look at. Worth an experiment I guess.

You can melt it with acetone.
