From the Diary

Thirty-year concrete. Another innovation from those Columbia cadres. Something about the atomic structure of the silica. Stronger than any regular concrete. At least for a while. But then both brittle and tending to crumble. Of all the supposedly peer-reviewed articles in engineering journals advocating its use, only two suggested that possibility. Maybe it was just the Seventies. I mean, everyone was high. Or maybe they just weren’t paying attention. After all, 30 years is a long time. Until it's gone.
