Slake Durability Apparatus

Slake Durability Apparatus is used in simulated weathering tests to determine abrasion resistance in wetting and drying cycles of shale and similar soft rocks in embankments and other construction-related applications. In the test, samples are alternately tumbled in mesh drums through a water medium and oven-dried for two cycles. The fines resulting from the agitation of materials is the Slake Durability Index.

The device consists of a double-ended motor drive unit that rotates two 5.5x3.9in (140x100mm) dia.xW sturdy wire mesh drums at 20rpm in water tanks. Two water tanks are included with the SA-80 and have built-in, quick-release drive units.

The 4ft (1.219m) long base accommodates two additional SAA-30 Water Tank and Drum Assemblies for increased productivity when testing. A set of two SAA-31 Wire Mesh Drums is also available separately to allow for more sample preparation.
