The long-expression sturdiness of Roman concrete buildings was identified to be due to existence of pyroclastic (volcanic) rock and ash within the concrete combine. The crystallization of strätlingite (a fancy calcium aluminosilicate hydrate)[26] during the development on the concrete and its merging with comparable calcium–aluminium-silicate–hydrate structures assisted provide the Roman concrete a better degree of fracture resistance when compared with modern concrete.

After the concrete is put, it goes through a curing approach to permit it to gain power and longevity. Curing involves maintaining right humidity ranges and temperature problems for a selected period, generally quite a few days or even weeks.
