Aggregate Crushing Value Civil Engineering

Aggregate Crushing Value Test Civiconcepts Sampling for aggregate crushing value test for the aggregate crushing value test an aggregate sample passing through 125 mm is sieve and retained on 10mm is sieve is selected and dried to a temperature of 105 c to 110 c then cooled to room temperature to fill the cylindrical measure mould about 65 kg of a sample of aggregate is sufficient Aggregate Crushing Value Test Step By Step Procedure The aggregate whose crushing value is less than 30 can be used for cement concrete road the aggregate whose crushing value is less than 40 can be used for wearing surface this test must be done before it comes to road and pavement construction calculation table for aggregate crushing value test Aggregate Crushing Value Test Significance Test Significance of aggregate crushing value test the crushing value test is conducted on aggregates that are used for the construction of roads lower crushing value aggregates give much more durability for roads due to its lower crushed fraction under the compression load the road is subjected to motion pressure continuously How To Find Aggregate Crushing Value And Its Test The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load the aggregate crushing value test is a useful guide when dealing with aggregates of unknown performance particularly when lower strength is suspected
