Methodology For Los Angeles Abrasion Test
The Los Angeles Abrasion Test is a widely-used method in India for determining the abrasion resistance of aggregates for concrete, standardized under IS 2386 (Part IV): 1963. The test involves running a sample aggregate through a specific number of revolutions in a Los Angeles abrasion testing machine and calculating the weight of the sample that remains on a 1.7 mm sieve. The average results of these tests determine the aggregate’s abrasion value, with a lower percentage signifying better abrasion resistance.
