The AFS 224811S Friability sand test will be taught in this module In addition the AFS 225100S Riddling Molding Sand and AFS 522213S AFS 2 in Dia x 2 in Specimen Preparation Rammer Method tests are part of the Friability test and included in this module

Silica sand 5070 used in ASTM G 65 threebody abrasion test before testing However the nature of wear scars produced by the twobody ASTM G 174 test and the three body ASTM G 65 test indicated that both tests removed material by a mechanism of scratching abrasion

The erosive particles used are AFS 5070 silica sand grains with a size range of 212–300 μm They are more uniform and less angular than the very abrasive solids with an average size of 170 μm that make up the predominant solids constituent in oil sand operations Download Download fullsize image Fig 4 AFS 5070 silica test sand

The abrasive slurry contained 10 wt of AFS 50–70 silica sand is continuously supplied with a flow rate of 18 lmin the distance between the spraying nozzle and a sample is 100 mm The duration time of testing is 120 min

Abrasive particles of silica sand with a mean diameter of 212 μm–300 μm AFS 5070 at wheel rotation speed of 200 rpm were used The morphology of silica sand shown in Fig 1a reveals angular shape of silica grains and the EDS analysis of silica sand depicts silicon and aluminum as the main constituents The flow rate of silica sand was kept as 350 ± 25 gmin at normal load of 130 N and
