What is hydraulic lime?

Hydraulic limes set by hydrolysis, they rely on moisture to cause a set. This gives them the ability to set underwater.

Absolutely not, hydraulic lime sets just fine. It is often confused with hydrated lime which can be added to cement mortar to increase workability. Genuine traditional lime mortars, renders and plasters don't ever contain any cement.
