The most frequently used test method is the Los Angeles Abrasion Test. . The principle of Los Angeles abrasion test is to find the percentage wear due to relative rubbing action between the aggregate and steel balls used as abrasive charge. . According to Production Methods . Natural Aggregates: . – Taken from native deposits without any change in their natural states during production except for crushing, grading or washing. . – Example: sand, gravel, crushed stone, lime rock. .
