The Los Angeles Abrasion test is used to indicate aggregate toughness and abrasion characteristics. The test subjects a coarse aggregate sample to abrasion, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. After being subjected to the rotating drum, the weight of aggregate that is retained on a specified sieve is subtracted from the original weight to obtain a percentage of the total aggregate weight that has broken down and passed through. Therefore, an L.A. abrasion loss value of 40 indicates that 40% of the original sample passed through.
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.
