Bonding polystyrene to concrete
Bonding polystyrene to concrete
(OP)
Hello
I am wanting to sandwich a dense-polystyrene-board between two skins of concrete and I am seeking an adhesive that will bond the polystyrene to the concrete. The adhesive will be subjected to some horizontal-strain but not excessively.
Any pointers would be appreciated.

Can you roughen the surface of the insul. panel a bit to improve the bond btwn. the conc. and insul. a little? That is, knife or scratch marks, not loose insul. dust. I would have this discussion, ask this question, of a few of the reputable structural adhesive manufacturers. They know their various products better than we do and should have some testing to back it up.

I really like your new ‘sign-off ,‘ ’signature’ art work, a great addition to your usual fine posts. But, the question is, do you know any wire hookers?

I thought all hookers were wired!

That sketch sure looks like a manufactured sandwich panel that is quite efficient to make and will have more reliable structural properties. Sometimes , the wire is a part of a truss that is inserted into a wall panel (cast, not extruded) that is common in the old soviet construction and typically uses lightweight concrete on one side and normal weight on the other side.
They liked massive construction back in the day. Where else would you see a masonry prism that was 1Mx1Mx2M or a perforated sandwiched wall panel tested vertically (long dimension horizontally) to measure the in plane flexural strength? Even the test engineers shook their heads.

Thanks for the advice. The slab will be poured in two stages, the bottom allowed to set before laying the polystyrene and top layer.
