  • Aggregate Crushing Value Test -Determine Aggregate

    Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions. Aggregate crushing value is a numerical index of the strength of the aggregate and it is used in

  • Aggregate Crushing Value Test L & T Learning Technology

    The aggregate crushing value is a numerical index of the resistance of an aggregate to crushing under a gradually applied compressive load. It is expressed as the percentage by mass of the crushed (or finer) material obtained when the test sample is subjected to a specified load under standard conditions. Aggregates with lower crushing value indicate a lower crushed fraction under load or higher strength and would provide a longer service life to the structure. Weaker aggregates if used in

  • Aggregate Crushing Value Test Procedure And Result

    “Aggregate Crushing values is a relative resistance of aggregates to crushing under gradually applied compressive load” In situations, when aggregate value 30 or higher the result may be a mistake and in such cases, the “ten percent fines value” should be determined and used instead.

  • Aggregate crushing value test Step by Step Procedure

    Important points to remember It is recommended that the crushing value of aggregate should be less than 30%. If it is more than 30 % then 10% finer aggregate is suggested to use. The aggregate whose crushing value is less than 30% can be used for cement concrete road.

  • Aggregate Crushing Value Test Procedure And Result

    For this reason assessment of strength of the aggregate is made by using a sample of bulk aggregate in a standardized manner. This testing method is known as an aggregate crushing value test. Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load. Generally, the test is conducted on aggregate passing 12.5 mm and retained on 10

  • CIVIL QUALITY CONTROL LAB: AGGREGATE CRUSHING

    The cylindrical measure is filled by the test sample of aggregate in three layers of approximately equal depth, each layer being tamped 25 times by the rounded end of the tamping rod. After the third layer is tamped, using the tamping rod as a straight edge levels off the aggregate at the top of the cylindrical measure. About 6.5kg of aggregate is required for preparing two test samples. The test sample thus

  • How to Determine the Aggregate Crushing Strength

    The aggregates passing through 12.5mm and retained on 10mm IS sieves are selected for finding aggregate crushing strength. After sieving aggregates, a cylindrical measure is taken and find the empty weight of cylindrical measure(We).It is then filled with aggregates in three layers with 25 blows to each layer using a tamping rod.
