Chemical (acid?) to soften a niche or concrete so hard to break?
dalton asked:
I’ve seen a round concrete with more or less 4 meters in diameter and about 18 inches thick broken into 3 from a foot of a mountain. Visible from one piece are 7 empty casts probably from gold bars and 2 empty cast contained probably metal box measuring 6 x 6 x 12 inches. We thought a chemical was used to break the concrete.
Now, a friend found a niche down a river. It appeared after an erosion due to a flood. It’s so hard to break. Anyone here knows what kind of chem is that used to soften concrete?
