Which outcome resulted from using lower-quality concrete in Roman aqueducts?

💡 Explanation

Increased hydrostatic pressure occurs because of increased permeability within concrete; therefore, water seeps into cracks and pores, causing premature structural failure due to increased hydrostatic pressure, rather than reduced expansion.
