The Klingons gave me a new kink
They are comparing roman concrete to portland cement, the most common formula. The kind of strength being emphasized is durability, because roman concrete has unique chemistry that allows small cracks to fill themselves. Modern special-purpose concrete blends can outperform roman concrete in other measures of strength, however.
