Portland Cement on Model Railroad Layouts?

[Trucklover]

A couple of years ago, Model Railroader did run an article, using light weight cement(Is there such a thing?) ,
The guy made molds to make a modern poured concrete emabankment wall.
You might have to go to MR website and look it up. Old age has given me a memory lapse as to when it was published.

I just did a search on MR's website and i couldnt find anything Maybe i wasnt searching in the right place or with the right keywords, but all i was getting was news articles, no actual articles from previous issues. Is there somewhere else to search the database for articles from previous issues?
