The crushed aggregate is then sieved weighed and compared to the original total weight to provide an aggregate crushing value Impact test determines the resistance of aggregates to impact forces Multiple layers of sieved samples are tamped 25 times before a 14 kg hammer is dropped for a total of 15 blows The resultant sample is sieved
Correlation analyses among the measured parameters identified the aggregate crushing value as a promising alternative test method to quantify the crushing potential of aggregates and to adjust the gradation accordingly to produce mixtures with
This document describes the procedure for determining the aggregate crushing value ACV of aggregate materials The ACV test involves crushing a sample of aggregate between and under a gradually applied 400kN load The percentage of material crushed finer than is calculated and reported as the ACV The test can be performed
The Aggregate Crushing Value ACV Test Set provides a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Each set consists of steel cylinder plunger base plate cylindrical measure and tamping rod All parts of the apparatus are powder coated or galvanized steel heat treated and ground
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
