The ‘ aggregate crushing value test gives a relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Aggregate crushing value is defined as the percentage by weight of the crushed or finer material obtained when the test aggregates are subjected to a specified load under standardized conditions and the strength of the aggregate used in road
Contact Us NowThis testing method is known as an aggregate crushing value test Aggregate crushing value test provides the resistance of an aggregate sample to crushing under gradually applied compressive load Generally the test is conducted on aggregate passing 125 mm and retained on 10 mm sieve
Read MoreThus coarse aggregates with a maximum size between 19 mm 3 4 in and 375 mm 1 1 2 in may be tested by Test Method C535 or Test Method C131C131M 12 The values stated in either SI units or inchpound units are to be regarded separately as standard
Read MoreAGGREGATE CRUSHING VALUE This test helps to determine the aggregate crushing value of coarse aggregates as per IS 2386 Part IV – per is code it should not be more than 25 for wearing surfaces 45 for non wearing surfaces
Read MoreBS 812 part 110 describes a method to determine the aggregate crushing value ACV which gives a relative measure of the crushing resistance of aggregate under an increasing compressive load The method is applicable to aggregates passing a 140 mm test sieve and retained on a 100 mm test sieve An aggregate specimen is compacted into a steel cylinder fitted with a nofriction plunger
Read MoreThe aggregate crushing value ACV provides relative measure of the resistance of an aggregate to crushing under a gradually applied compressive load Two versions available 150 standard and 75 mm dia The apparatus comprehend cylinder plunger base plate tamping rod and measure Cylinder plunger and base plate are made from special alloy steel hardened to 650 HV 578 HRC and
Read Moreive 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 tus Required
Read MoreThe 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
Read MoreThe 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
