DEFINITION

Classification: 524/2

Water settable inorganic compound as nonreactive material:

(under subclass 1) Subject matter wherein the added nonreactant material is an inorganic material hardenable by hydration to produce a solid mass, e.g., Portland cement, gypsum cement, etc.

(1) Note. This subclass takes an inorganic material claimed or disclosed by the term "cement" or "setting agent", e.g., aluminum oxide cement, etc.
