@Ian MacMillan is who introduced me to Quickrete years ago. He used a ton of it on his previous layout, mainly in bridge abutments. The beauty of it is that you can build a mold and the cement will match all the relief in the mold, so in essence is scales down very well. It can be used to simulate newly poured concrete as well as distressed concrete, and you don't have to paint it because it's the real thing. Just weather as desired. I used it for station platforms and loading docks, and if I need it for bridge abutments in the future I definitely will use it for that as well.
