Which outcome occurs regarding a fortification wall when Roman cement's pozzolanic reaction slows significantly because lime source is impure?

💡 Explanation

Increased tensile stress cracking results within the concrete because the hydration process is weakened in the absence of high quality component materials (calcium hydroxide). Therefore, overall wall strength weakens, rather than strengthens, with material degradation in the binding cement. The relevant mechanism is loss of chemical hydration.
