Cement "Melter"

The invention of "Cement" gave a new meaning to the way Architecture was perceived. Things have now gone to the next level, from use of plain cement to a mix of reinforcing structures, metals, composites and such, to come up with marvels. However, a few days back, in my office kitchen as a repair work was initiated, four or five tiles had to be removed. Yes, you guessed it right. I know the tiles could be glued to the wall or cemented into the structure. In this case, the tiles were cemented.

That made me wonder if a such chemical existed that could "melt" cement, or perhaps soften it enough to enable a "non-destructive/not-so-destructive" repairs. The implementations could be taken any distance, right from bringing tiles in a bathroom or kitchen down to bringing entire buildings down swiftly. The advantage? Only the cement goes and you manage to rescue everything else, bricks, wood, and perhaps the metal bars as well, which could be "re-used". It also gets rid of the noise pollution coming from the drills in case of huge concrete blocks, and the "air-pollution" from the smoke rising high-up in the air.

Just a thought. What do you think?
