Knowing how to do it versus know why it does

What the ancient Romans couldn’t have known, though, is how crystals of the mineral leucite, which is rich in potassium, in the volcanic aggregate would dissolve over time to beneficially remodel and reorganize the interface between volcanic aggregates and cementitious binding matrix, improving the cohesion of the concrete.
“It turns out that the interfacial zones in the ancient Roman concrete of the tomb of Caecilia Metella are constantly evolving through long-term remodeling,” Masic says. “These remodeling processes reinforce interfacial zones and potentially contribute to improved mechanical performance and resistance to failure of the ancient material.”
the construction was of a process not of a fixed end result.
There is no fixed thing there is a process. so one constructs not a house but a thing that is ‘housing’ as a gerund.
