Aggregate Crushing Value Test -Determine Aggregate . 2010-05-05· 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.

The aggregate crushing value (ACV) provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. Two versions available: 150 (standard) and 75 mm dia. The apparatus comprehend cylinder, plunger, base plate, tamping rod and measure.

We have objective of aggregate crushing value test,May 08 2013 · Aggregate Crushing Value Test Appratus Preparation of sample Test sample consist of aggregate passing a 125mm IS sieve and retained on a 10mm IS sieve The aggregate to be tested is dried in oven for a period of not less than 4 hours Procedure

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. 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.

Jan 25, 2018· Indian Roads Congress and ISI have specified that the aggregate crushing value of the coarse aggregates used for cement pavement at surface should not exceed 30 percent. For aggregates used for concrete other than for wearing surfaces, the aggregate crushing value shall not exceed 45 percent, according to the ISS.

22-2-2010· Determination of Aggregate Impact Value Assess their suitability in road construction on the basis of impact value. Aggregate Impact Value on Coarse Aggregates Apparatus for Aggregate Impact Test. The apparatus as per IS: Aggregate Crushing Value Test Determine Aggregate Crushing Strength.

An aggregate specimen is compacted into a steel cylinder fitted with a no-friction plunger. The specimen is then loaded via the plunger. The load crushes the aggregate to an extent depending on the crushing resistance of the material. It is measured by a sieving test on the crushed specimen and it is a measure of the aggregate crushing value (ACV).

In road construction, the quality of aggregates is assessed by the crushing strength of aggregates.For higher quality of roads, the aggregate should possess low aggregate crushing value. Here I am going to teach you how to determine the crushing strength of aggregates.First, let us check what are the various apparatus needed for this experiment.
