No, it's fact based on figures from the USGS published in early 2014.
In the above stories the words are used interchangably, but the fact remains. China made more cement/concrete between 2011 and 2013 than did the US in all of the 20th Century (at least according to the USGS). Other stories I read had Bill Gates citing the USGS as his source of information. Why anyone would have to cite Bill Gates citing the USGS I don't know, but it does make a story a bit more interesting.

BTW, some people and sources get confused between the meanings of "concrete" and "cement". To be clear, concrete is hard and dry. It comes from cement, which includes aggregate and a binding agent that is usally mixed with water. The process of making cement into concrete can generate a lot of heat, which is why the "setting" of large amounts has to be monitored and even cooled in place sometimes for decades.
As to LBSR, where were the sellers today? I want sellers while I accumulate. Even on a "normal" day, volume sucks. What's up with these people who will not part with their shares? Geesh!
