Aggregate Abrasion Value AAV Testing Machine

STANDARDS : EN 097-8; BS 8 2- 3. The Aggregate Abrasion Testing Machine is used to determine the Aggregate Abrasion Value AAV by testing the measure of. the resistance of aggregates to surface wear by abrasion. Los Angeles Abrasion Value – The Omega Group 222222 Los Angeles Abrasion Value. The Determination of resistance to Fragmentation. This test is carried out in accordance with BS EN 097-2 and has two methods the most commonly used and well known Los Angeles test and the impact test method. The test is used to determine the wear of aggregates used in building and civil engineering sector.

AGGREGATE ABRASION VALUE AAV - GEOTECHNICAL

The Abrasion Machine is used to determine the Aggregate Abrasion Value AAV by testing the measure of the resistance of aggregates to surface wear by abrasion. The Abrasion Machine consists of a flat circular cast iron grinding lap wheel of 600 mm dia. which rotates in a horizontal plane at a speed of 28-3 r.p.m. Buy Aggregates - Search Buy Aggregates

This British Standard a part of the BS 8 2 series describes a method for the determination of the aggregate abrasion value AAV which gives a measure of the resistance of aggregates to surface wear by abrasion. The aggregate abrasion value is determined from the differences in mass of the specimens before and after abrasion.

LOS ANGELES ABRASION VALUE OF AGGREGATE

percentage of the original weight of the test sample. This value is reported as the percentage of wear. Aggregate Abrassion Value = A-B /A X 00 where A = weight in gm of oven-dried sample. B = weight in gm of fraction retained on .70 mm IS Sieves after washing and oven-dried upto constant weight. 6.Video Los Angeles Abrasion Test

Aggregate Abrasion Test Engineering Basic To carry out the aggregate abrasion value test the following are the procedures used: . The cover of the machine is remove and the sample x and y is pour above into the machine. 2. The abrasion charges is place on the sample and the cover is fix back firmly. 3. The machine is switch on and it is allow to undergo 500 revolutions at 28 – 30rpm.
AGGREGATE ABRASION VALUE MACHINE - AAV - Dorry Abrasion Machine The percentage loss in mass of chippings as known as the & 39;Aggregate Abrasion Value& 39; AAV and ranges from about for hard flints to over 6 for aggregates normally considered too soft for use in road surfacings. Related Test The PSV test Polished Stone Value requires an AAV determination when PSV is greater than 60.
