C068 Angeles Abrasion Testing Machine,los angeles abrasion machine

Measureunder the standard condition,coarse aggregate (sand) resistance to friction and impact , abrasion loss expressed by percentage . Los Angeles abrasion loss method is an important index, especially for the stones using performance of concrete and asphalt mixture and grass-roots stone rutting resistance, compressive strength, abrasion resistance and durability are closely related. Usually small aggregate of abrasion loss is stiffness, durability, but contains more weak particle s concentration, weathering more serious, stone smash seriously after abrasion test, Los Angeles abrasion tester is an important waystochoose good stone.
