Low Aggregate Crushing Value Indicates Strong Aggregates

Calculation of aggregate crushing value The aggregate crushing value is defined as the ratio of the weight of fines passing through specified IS (here 2 36mm sieve) to the total weight of sample expressed in percentage W1= Weigh of the total aggregates (Wa We) W2= Weigh of aggregates passing through 2 36mm IS sieve.Aggregates Low aggregate crushing value indicates strong aggregates as the crushed fraction is low Thus the test cans be used to assess the suitability of aggregates with reference to the crushing strength for various types of pavement components The aggregates used for the surface course of pavements should be strong enough to withstand the high stresses due to wheel loads including the.

Aggregate Crushing Value (ag 210) – Alfa Testing

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).The Aggregate Crushing Value (ACV) Test Set measures how resistant an aggregate is when being crushed under a gradually applied compressive load Each set consists of steel cylinder plunger base plate cylindrical measure and tamping rod For durability and reliability all parts of the apparatus are galvanized steel or powder coated heat.

How To Determine The Aggregate Crushing Strength Value

This resistance of aggregate may differ from resistance to gradual load which we measure in the crushing value test Importance Impact Value Test Generally the majority of the aggregate test is carried out to know the response of aggregates to different kinds of loads that the aggregates will be subjected to during their service life.With aggregate of aggregate impact value higher than 30 the result may be anomalous Also aggregate sizes ‘larger than 14 mm are not appropriate to the aggregate impact test The standard aggregate impact test shall be made on aggregate passing a 14 0 mm BS test sieve and retained on a10 0 mm BS test sieve.
