HOW AGGREGATE PROPERTIES AFFECTS CONCRETE PROPERTIES ...

Aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load. The aggregate crushing value should not exceed 45% for aggregate used for concrete other than for wearing surfaces, and 30 % for concrete for wearing surfaces, such as runways, roads for pavements.

How to Find Aggregate Crushing Value and Its Test Procedure?

Aggregate Crushing value is a measure of the strength of the aggregate. The strength of concrete largely depends upon the strength of aggregate. The aggregate should therefore have minimum crushing value. The aggregate crushing value provides a relative measure of the resistance of an aggregate to crushing under gradually applied crushing load.

Aggregate Crushing Value CivilArc

The aggregate crushing value provides a subjective measure of the resistance of the aggregate crushing in the pressure of the progressively smeared compressive load. When the aggregate crushing value is 30 or greater the outcome can be irregular and in those kind of circumstances the ten percent fines value has to be assessed in its place.
