11/24/2014· • Attrition test: The aim of this test is to determine the resistance of the stone to abrasion, specially for those stones which are to be used for path ways, pavements and roads subjected to the grinding action of the traffic. percent wear= (M1-M2)/M1*100 Where; M1= Initial mass of stone ballast.

Table showing the relationship between weights and crushing strength. It is the ability of a stone to endure and maintain its essential and distinctive characteristics i.e. resistance to decay, strength and appearance. Physical properties such as density, compressive strength and porosity are measured in order to determine its durability.

Aggregate crushing value test on coarse aggregates gives a relative measure of the resistance of an aggregate crushing under gradually applied compressive load. Coarse aggregate crushing value is the percentage by weight of the crushed material obtained when test aggregates are subjected to a specified load under standardized conditions.
