Cube Test Crushing Value

This test is repeated once or twice and the average crushing value of the aggregate is determined. The average crushing value in the different tests is the actual crushing value of aggregate. Important points to remember. It is recommended that the crushing value of aggregate should be less than 30.

  • Crushing Strength Geology Britannica

    Brittle materials such as rock, brick, cast iron, and concrete may exhibit great compressive strengths but ultimately they fracture. The crushing strength of concrete, determined by breaking a cube, and often called the cube strength, reaches values of about 3 tons per square inch, that of granite 10 tons per square inch, and that of cast iron from 25 to 60 tons per square inch.

  • Aggregate Crushing Value Test Civiconcepts

    Sampling for Aggregate Crushing Value Test For the Aggregate crushing value test, an aggregate sample passing through 12.5 mm IS sieve and retained on 10mm IS sieve is selected and dried to a temperature of 105 186C to 110 186C then cooled to room temperature. To fill the cylindrical measure mould about 6.5 kg of a sample of aggregate is sufficient.
