Verdict: COMMON KNOWLEDGE · 0 sources for, 0 against · Last checked

The analysis

The statement describes the fundamental chemistry of hydraulic cements (such as Portland cement), which react with water to form hydration products (like C-S-H gel) and can set and harden underwater. This is a basic, textbook property of hydraulic cement and does not require empirical citation from the retrieved literature.
