aggregate crushing value

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
