SLAKE DURABILITY, Cat No: AG34-108
SLAKE DURABILITY ASTM D4644
Slake
durability is a simulated weathering test to determine abrasion
resistance during wetting and drying cycles of shale and similar soft
rocks as used in embankments and other construction-related
applications.
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. This
apparatus consists of a base-mounted, double-ended motor drive unit
which rotates two 140mm dia. x 100mm (5.5x3.9in) sturdy wire mesh drums
at twenty revolutions per minute in included water tanks.
The
water tanks have built-in, quick-release drive units. Corrosion
resistant drums are constructed of 2mm opening mesh with solid end
plates.
The unit is capable of turning four drums
simultaneously at the specified rpm, and is mounted on a 4ft (1,219mm)
long base suited to the addition of the added drums in series with the
first two. An additional set of two mesh drums and two water tanks are
available as AG34-108/SAA-30. To facilitate sample preparation, order
additional mesh drums as AG34-108/SAA-31.
Dim: 48x14x9.25in (1,219x355x235mm), LxWxH
