Hello, I am curious to know if anyone can tell me how to dissolve a block of concrete....? I have about three tons of concrete massed in my back yard, and I hope to simply dissolve it by chemistry. Is there an acid that will break the concrete down over time, say a months time, that would do the trick?

 

Any ideas? Thanks alot!

That would be horribly damaging to everything living in your yard, and probably the land around it as well.

 

Have you considered looking for a local concrete recycler? It's becoming a lot more common to recycle it these days:

Forget about dissolving it. Although I am sure it is possible, I am also fairly sure that anything that can do it will kill all life forms within sight for the next century or two. Just dig it up and, if possible, have it recycled.
