PPT--Abrasion: Abrasion of aggregates measures the resistance of aggregates against wearing.

It is an important property of concrete in roads and in floor surfaces subjected to heavy traffic 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 .
