  • abrasion index test for limestone

    for low- density limestone to 10.3 for granite. The abrasion test of ASTM C241-90 (1997) result in an index number proportional to the volume of material abraded or worn off the stone during the stone test. The abrasion index numbers are scaled to generally range between 0 to 100. There are two concerns regarding this test method.get price

    Oct 12, 2011  The wide-wheel abrasion test involves pushing a rotating wheel on to which an abrasive grit is fed against the test stone. This is carried out for a set amount of time under a set loading and a set flow rate of the abrasive. At the end of the test the length of the groove that has been cut is measured to give the abrasion resistance value.
