  • Los Angeles Abrasion Test on Aggregates -Values for ...

    Los Angeles test is commonly used to evaluate the hardness of aggregates. The test has more acceptability because the resistance to abrasion and impact is determined simultaneously. Depending upon the value, the suitability of aggregates for different road constructions can be judged as per IRC specifications as given:

  • Estimation of Los Angeles abrasion resistance of

    Aggregates are one of the most common materials used in engineering projects, and they are exposed to a variety of physical and chemical influences depending on the areas in which they are used. An aggregate should generally be hard, durable, uniform and clean, as well as highly abrasion-resistant. It must not contain harmful substances that can cause alkali-silica reactions.
