City bridges eventually crack from stress and weather. But researchers studying ancient Roman harbor ruins found that their concrete seems to "heal" small fractures when seawater seeps in. Recent lab work reports a similar effect in modern trial mixes that include tiny lime-rich clasts and pozzolanic ash, with microcracks closing over weeks in brine. Engineers say this parallel points to an accessible path to longer-lasting highway bridges, potentially reducing maintenance closures and costly emergency repairs.

When materials scientist Lila Moreno and her team described healing-like behavior in their modern mixes, the claim drew interest. Yet, as they emphasized, the chemistry appears to depend on slow marine interactions not typical of bridge decks, and the role of the clasts is not fully established. Moreno has compared the clasts to "seeds" that may release binding material under certain conditions, but how this would work in everyday bridge environments remains uncertain.
Based on the texts, what would the author of Text 2 most likely say about Text 1's characterization of the modern-concrete finding?
