The prolonged-expression sturdiness of Roman concrete structures was discovered to become because of the existence of pyroclastic (volcanic) rock and ash during the concrete blend. The crystallization of strätlingite (a fancy calcium aluminosilicate hydrate)[26] through the formation in the concrete and its merging with identical calcium–aluminium-silicate–hydrate constructions helped give the Roman concrete a larger diploma of fracture resistance compared to modern day concrete.
