Which outcome results when the Roman's 'opus caementicium' mix deviates significantly from its standard recipe for bridge construction?

💡 Explanation

Reduced compressive strength appears when the hydraulic concrete mixture varies substantially in its recipe, because the hydration reaction will proceed with reduced efficiency. Therefore lower compressive strength results, rather than other properties enhanced by design mix.
