The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load With aggregate of aggregate crushing value 30 or higher the result may be anomalous and in such cases the ten percent fines value should be determined instead 2 apparatus required
This paper reports an experimental investigation carried out to establish a mathematical relationship between aggregate crushing value ACV and ten percent fines aggregate crushing value TFV for some aggregates in Nigeria

Ten Fines Value Of Mm Aggregate Ten percent fines aggregate crushing value henan 10 per cent fines aggregate crushing value is the force in kn required to crush a sample of 13295mm aggregate so that 10 per cent of the total test sample will pass a 2 36 mm sieve aggregate crushing value civilsutrain aim to determine the aggregate crushing value
this method is the Ten Percent Fines Value TFV which is also a measure of the resistance of an aggregate to crush ing under a gradually applied compressive load with the
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load With aggregate of aggregate crushing value 30 or higher the result may be anomalous and in such cases the ten percent fines value should be determined instead 2 apparatus required

For other size fractions a recommended method is described in appendix A The method is not suitable for testing aggregates with an aggregate crushing value higher than 30 and in such cases the method for ten per cent fines value described in BS 812 111 is applicable
The aggregate crushing value gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Crushing value is a measure of the strength of the aggregate The aggregates should therefore have minimum crushing value 3 APPARATUS The apparatus of the aggregate crushing value test as per IS 2386
