Stone Adhesive
Stone Adhesive
(OP)
Stoneworks weight a lot and the back side is very smooth.. do you trust the so called stone adhesive is enough to hold the stone works for long time?
When was the last time you drove down the highway without seeing a commercial truck hauling goods?

If small pieces of stone or faux stone, cementious adhesive (thinset) or mortar can be used. Follow the instructions provide by the Masonry Veneer Manufacturer's Association guide (a copy is attached).

However, bear in mind that the panel that collapsed was to be held in place with epoxied bolts; it was more poor execution that caused the failure.

If you want to give nature a sporting chance to kill you, take a drive through the Rocky Mountains. Eventually, if you drive long enough, you may get your wish but most of us don't really want to risk getting squashed as we go about our daily business.

The panel of natural stone each weights about 10 lbs and it uses polymer modified mortax mix for adhesion and if even one piece falls down. It can be completely fatal so I can't imagine having it installed.
Does anyone know where to purchase aluminum design that looks like stone and almost indistinguisable from stone in appearance but entirely aluminum?
Attached is the stone works (size 2.7 meters height and 2 meters horizonal) I want to emulate but made of aluminum or even plastic adhere to concrete external wall.
RE: Stone Adhesive
I can see the concern of gluing it in an overhead position, but as a wall the weight is supported by the next stone down, and ultimately the foundation.
RE: Stone Adhesive
Good point! Life's risky enough without adding unnecessary risk.
I'm told that air brakes on trucks require energy to hold the breaks off. Therefore if the mechanism fails, the brakes engage. I don't know if that's true but, if so, I like it. That is, if the system fails it becomes safer, so to speak. Brilliant! But that's the opposite philosophy of suspending rocks, anvils, grand pianos, etc. above our heads...though it does make for some entertaining coyote/roadrunner cartoons...
RE: Stone Adhesive
The 2.7 meters vertical and 2 meters stone design is suspended above in the second floor just below the ground floor entrance to a commercial store. It's not continuous down.
How can polymer modified mortal mix support 10-20 lbs piece to a vertical concrete wall (even roughen)??

As for these blocks, if there are no concerns about earthquakes, that's one thing, but without even pins, you count solely on the shear strength of the adhesive and the support of whatever's directly underneath. Seems to me that epoxied pins would at least provide some level of cantilevered support of the block and not just depend on the adhesive alone.

RE: Stone Adhesive
Perhaps so, but BA's point remains: if you don't suspend something above your head in the first place then it can't fall on your head.
Failures occur and we'll never be able to eliminate all risk from life. But whether gluing heavy slabs of ornamental stone above our heads for purely aesthetic purposes is a wise decision is another question.

RE: Stone Adhesive
I wasn't attempting to contradict that. But, not everything is solely about functionality; if it were, the world would resemble a Brutalist architecture catalog. My house, on the other hand, has decorative rock work panels that are glued on and goes up the walls to the bottom of the 2nd floor.

RE: Stone Adhesive
It's not a structural component...at least, the stone isn't. The epoxy anchors arguably are, I suppose. But therein lies the rub. For a structural component such as a column or beam to fail it likely means that there has been dramatic design or construction incompetence or oversight, and even then there are often warning signs before it occurs. Epoxy anchors, on the other hand, only require a little bit to go wrong (dust in hole, water intrusion, etc.) for one of them to fail and then they do so with no warning. Add to that that in the scenario under discussion there could be hundreds or even thousands of them installed, and all it takes is for one of them to go wrong...a la the Boston tunnel incident. It's a lot of risk to take for a simple avoidable architectural element, in my opinion. We can't build things without structural components but we don't have to glue heavy stones above our heads.
But, at some point it comes down to our respective levels of risk aversion. I'm of the philosophy that I won't have a skydiving accident if I don't go skydiving. For others that particular adrenaline rush is worth the risk. We each make our own choices.
RE: Stone Adhesive
I guess to answer the original question as written: I wouldn't just blindly trust the adhesive, I would want the hard testing data to back it up before I, as a structural engineer, gave the OK.

RE: Stone Adhesive
What if you use pure A & B epoxy adhesive in attaching the 15 psf stone to the wall of the second floor above the entrance of ground floor? Would it attach better as bond strength is supposed to be on the order of above 2000 psi?
