Abstract

A classification scheme for classifying sized bridging materials is disclosed. The scheme identifies a durability metric for the sized bridging materials. The scheme then identifies a value range having a higher relative strength and a lower relative strength. The sized bridging materials may then be tested according to the durability metric and associated with a relative strength based on the durability metric determined during the test.
