This test is also known as the Los Angeles Rattler Test. B. REFERENCES
Soundness Test of Cement What is soundness of cement? The ability of cement to retain its volume after it gets hardened is known as Soundness of Cement. That means the cement should be at minimum volume change after it gets hardened. The test conducted to identify the excess amount of lime in cement is known as soundness test of cement.
The Los Angeles test is a measure of degradation of mineral aggregates of standard gradings resulting from a combination of actions including abrasion or attrition, impact, and grinding in a rotating steel drum containing a specified number of steel spheres. The Los Angeles (L.A.) abrasion test is a common test method used to indicate aggregate toughness and abrasion

NOTE 1-A procedure for testing coarse aggregate smaller than 37.5 mm (11⁄2 in.) is covered in Test Method C131/C131M. The values stated in SI units are to be regarded as the ...
The aggregates should therefore have sufficient toughness to resist their disintegration due to impact. This characteristic is measured by impact value test. The aggregate impact value is a measure of resistance to sudden impact or shock, which may differ from its resistance to gradually applied compressive load. Procedure of Aggregate Impact Test

Jul 29, 2015· Skid resistance is one of many important aggregate properties, the polished stone value test is performed on aggregate particles that pass a 10 mm sieve and retained on a 7.2 mm grid sieve.
Overview. The fine aggregate angularity (FAA) test (Figure 1) is an indirect method of assessing the angularity of fine aggregate. Fine aggregate angularity is important because an excess of rounded fine aggregate (often in the form of natural sand) can lead to HMA rutting.. Figure 1: Fine aggregate angularity test.

Jul 01, 2014· This test method covers a procedure for testing of coarse aggregates with a maximum size smaller than 37.5 mm ([1½ in.] for resistance to degradation using the Los Angeles testing machine (Note 1). NOTE 1-A procedure for testing coarse aggregate larger than 19.0 mm [¾ in.] is covered in Test Method C535.
Regardless of which method you choose, abrasion testing serves as a great indicator for how your materials will react to wear and tear over time and will be an important aspect of your quality control process. Stay tuned for our follow-up blog post, Aggregate Abrasion Testing Part II: The Los Angeles Abrasion Test Method.
For example, ASTM D 692, Coarse Aggregate for Bituminous Paving Mixtures, specifies 5 cycles and a maximum percent loss of 12 percent when the sodium sulfate is used or 18 percent when the magnesium sulfate is used. Typical Values. Typical values depend upon the type of soundness test used.
As an alternative to the 10 "o fines test, the aggregate impact value may be carried out in accordance with BS 812 : Part 112. The oven-dry aggregate impact value shall not exceed the appropriate value given in table 2. Table 2.
