Does concrete take 100 years to cure?
Does concrete take 100 years to cure? No. Not on at least two basis points. Firstly, concrete only continues hardening for so long as the pore moisture value drops below a certain ill-defined value.
Is the concrete in the Hoover Dam still drying?
TIL that even after 78 years, the cement in the Hoover Dam is still curing. Curing would be the hydration process of cement. When preparing concrete, one mixes water, cement, sand, gravel and often some additives to impart special properties.
Does concrete ever stop hardening?
Curing times for concrete Technically, concrete never stops curing. In fact, concrete gets stronger and stronger as time goes on. But, as far as we’re concerned, to reach a practical strength, most industrial concrete mixes have a 28 day curing period.
