I was driving through a shopping mall parking lot the other day and noticed they were tearing up some sections to be replaced. And I noticed the big piles of large (bout 1'-2' x 1'-2') chunks of concrete they had removed, and it got me wondering if it could be reused as a building material. Kinda like an old fashioned stone building? I know it would be a lot of work fitting all those "stones" but if it could be gotten cheap enough the savings would make it worth it, I think (time I got.... Money not so much). So I was wondering if anyone had ever heard of or seen anything like this done before??? Any and all help/advice welcomed and appreciated, thanks .
