French term or phrase:beton arme en surpression
Type of construction. What exactly does "en surpression" mean here?
Explanation: This is a guess.
Article from the Scientific American:
"Jones discovered that exposing concrete mixed with portland cement to high-pressure CO2 drove water out of the material and changed its chemical composition. Standard compression tests, he says, show that on average the treatment increases the strength of portland cement by 84 percent. Subsequent experiments at Los Alamos National Laboratory have demonstrated that the process can transform a wide range of inexpensive materials--including some that are currently considered waste products--into stronger, more useful forms.
