You are actually retarded. I do maintenance for a living. One of the buildings on the property I work on is a cathedral made entirely out of concrete. The others have concrete basements. They're all old, with the newest one having been built in the 50s, and the first on the lot was built, if I remember correctly, in the late 20s. NONE of them are crumbling, anywhere, like what is seen in that clip. The fact that I have to pull out a rotary hammer every time someone wants me to hang a TV, whiteboard, or shelf, is proof enough of that.

Either cease trolling or do not breed.

>No, generally hack saws and oil are a bad combination and asking for injury.

What the fuck are you even on about? Lubricating a hacksaw blade is fine, and makes a huge difference in ease of cut in gummy materials like aluminum. Also helps in plastics that tend to melt and stick to the blade otherwise (PVC comes to mind).
