He said increasing the strength of cement allows manufacturers to use less concrete, decreasing not only weight but also the energy required to make it and the carbon emissions associated with cement’s manufacture.

My prediction is this will never be commercialized.
So what if it’s as slippery as ice. It will crack in pretty patterns.
Concrete bubbles are too heavy to float here on earth.
We were using 3M Scotchlite glass spheres to make floating 10,000 PSI concrete in the early 1990’s for our concrete canoes.
Failed to mention that it will greatly increase cost.
Concrete with river rocks (roundish) was abandoned long ago for crushed rocks (sharp corners). The sharp corners stop adjacent rocks from sliding past each other (until the corners crumble and the concrete cracks). Rounded rocks slide easily and crack at much lower loads.
This is fascinating technology. I could see it as an additive of concrete (building material). I do not see how it does the work of cement, however, to bond the aggregates.
