Which consequence follows if Vitruvius's concrete formulation lacks pozzolan?

💡 Explanation

Without pozzolan, the hydration process alters; lime reacts without silica creating calcium hydroxide--a weaker binder less resistant to weathering--via reduced tensile strength. Therefore, less durable concrete results, rather than faster setting or chloride vulnerability found with alternate formulations.
