Additives to the 1/2/3 common concrete mixture is common- like fiberglass, Styrofoam ( used in shooting ranges!) and poly beads of varying shapes is not what these idiots are talking about- seems they are replacing relatively inexpensive Portland cement ( CaO, SiO, AlO) with petroleum based stuff ( polymers and carbon nano stuff).
Likely will be IR degradable and unstable in many environments, just what we need.
Concrete has lasted since the Romans first used it in the 1st century BC ( yes, Before Christ, not BeforeCommonEra).
Concrete is a fascinating CE topic.
I poured a slab for a stoop in front of a door with concrete and a fiber additive. Hasn’t cracked yet. (4 years) The last one cracked with 2 years. Quite impressive.
