The Elongation Index of an aggregate is defined as the percentage byweight of particles whose greatest dimension (length) is 1.8 times their meandimension. This test is applicable to aggregates larger than 6.3 mm.
Database handle for the object. It is of XML type ID, so is constrained to beunique in the XML document within which it occurs. An external identifier for the object inthe form of a URI may be constructed using standard XML and XPointer methods. This is doneby concatenating the URI for the document, a fragment separator, and the value of the idattribute.
