[TowerTalk] re; exploding concrete

[Greenacres113 at aol.com]

I believe it's entirely possible. When you are a  novice learning arc welding 
 & gas cutting the first lesson is to place  the metal properly. If you weld 
or burn on concrete you can super heat the  trapped water inside. It will 
definitely explode. I have seen it happen.  Lightning super heating moisture as it 
passes along a wire/pipe in concrete can  cause this.
