A better title for this article is “seawater derived cement could marginally decarbonize concrete industry”

Not quite. Fiberglass and basalt rebar are making major progress because of the inevitable corrosion of traditional rebar.

> major progress

Can you link to an account of this progress where it indicates how much less carbon intensive they are vs steel in the majority of steel reinforced concrete use cases and how imminently they’re going to replace steel and how expensive they are and are likely to be?

Both of those reinforcement types have sudden failure modes and aren't commonly used for rebar because of this.
