The very long-phrase durability of Roman concrete structures was identified to get mainly because of the presence of pyroclastic (volcanic) rock and ash in the concrete mix. The crystallization of strätlingite (a complex calcium aluminosilicate hydrate)[26] throughout the development with the concrete and its merging with very similar calcium–aluminium-silicate–hydrate constructions assisted give the Roman concrete a higher degree of fracture resistance in comparison to modern-day concrete.
