Slake Durability Test Apparatus



Specification

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.
This test method has been developed to assess the deterioration of rocks over a period of time when subjected to water immersion.
The percent loss of mass is referred to as the slake durability index.
Samples are alternately tumbled in mesh drums through a water medium and oven-dried for two cycles.

The slake durability apparatus consists of a motorised drive unit which is mounted on a baseplate and which can rotate two or four drums at a speed of 20 r.p.m.
The test drums are manufactured from 2.00 mm mesh, 140 mm dia. x 100 mm long
The tank assemblies are filled with water to a level 20mm below the drum axis.
