specific gravity of crushed aggrigate

  • Specific Gravity of Coarse Aggregates: Its Importance

    The specific gravity of aggregates indirectly measures its density; hence it is the most essential parameter of strength or quality of the aggregates. Higher the specific gravity, higher is the strength. It is due to higher specific gravity there would be higher compressive strength of aggregates and hence it passes on to the concrete. 02.
