Hope this isn't a stupid question. Just reading this from PCA website:
http://www.cement.org/basics/concretebasics_faqs.asp
"Will concrete harden under water?
Portland cement is a hydraulic cement which means that it sets and hardens due to a chemical reaction with water. Consequently, it will harden under water."
that makes sense. but reading several posts here and elsewhere, hydraulic cement is typically described as a 'special purpose" type of cement that hardens very quickly (e.g. plugging a hole in a leaky block wall, etc.)
according to this PCA description, any type of Portland cement is "hydraulic cement" since it uses hydration (water) to cure. So the stuff I'm using to build a pier at camp is hydraulic cement (Portland type II).
sorry for the noise, but I'm just curious as to what is (or isn't) the proper use of the term "hydraulic cement". Or if it really matters...?
thanks
