Slake Durability Device

SA-80 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 percent loss of mass is referred to as the Slake Durability Index.

The device consists of a double-ended motor drive unit which rotates two 5.5x3.9in (140mmx100mm) dia. sturdy wire mesh drums at twenty revolutions per minute in water tanks. Two water tanks are included with the SA-80 and have built-in, quick-release drive units.

The 4ft (1,219mm) 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.
