Masonry Adhesive???

[Smufter]

Good morning,
Hope this is in the right section??
Don't know if anyone would be able to help me, but I have a masonry barbecue in my garden. A large branch fell from an overhanging tree and has smashed a couple of the upper slabs clean in half. The barbecue was supplied with special "Betonfast" silicone adhesive which has worked well, and I was hoping to repair the slabs with some of this. But a search has only found it on Amazon and they want about £50.00 for a tube!!

I'm not prepared to pay £50.00 for a tube of glue.....
Can anybody suggest an alternative that might work please?
I have attached a picture of the barbecue below (not mine!) and the two parts that are broken are the two top cross members, not load bearing but obviously subject to some heat.
Hope this makes sense, and just wondered if anybody had any suggestions??
Many thanks
Rob

Hi Andy
thanks for the quick response.
Would that stand the heat of the barbecue mate??

Not sure about the heat, but it is the strongest adhesive I have ever used. I used it on 2 bricks and no one could pull it apart.

At the end of the day give it a punt.

See if you can find the datasheet for that one at https://www.ob1original.com/data-sheets.html and it has the temperatures in.
