Improving the Jar Slake, Slake Index, and Slake Durability Tests for Shales

PAUL M. SANTI
Published: 01 January 1998
Environmental & Engineering Geoscience (1998) IV (3): 385–396.
DOI: https://doi.org/10.2113/gseegeosci.IV.3.385
...PAUL M. SANTI Abstract This study proposes modifications to three shale durability tests to improve reproducibility, reduce the level of effort required, and better correlate the test to actual slaking characteristics. Modifications to the jar slake test reduced test variability by one-third...

Published: 01 May 1987
Environmental & Engineering Geoscience (1987) xxiv (2): 247–258.
DOI: https://doi.org/10.2113/gseegeosci.xxiv.2.247
...D. N. RICHARDSON; JOHN D. LONG Abstract The slake durability index is used as an indicator of the durability of shale. Numerous modifications of the slake durability index test method have been proposed in an attempt to overcome some of its shortcomings. For the present report, five criteria were...

Assessing the durability of mudrocks using the modified jar slake index test

M. A. Czerewko, J. C. Cripps
Published: 01 May 2001
Quarterly Journal of Engineering Geology and Hydrogeology (2001) 34 (2): 153–163.
DOI: https://doi.org/10.1144/qjegh.34.2.153
...M. A. Czerewko; J. C. Cripps Abstract As exposure to weathering processes or other changes in moisture content can be the cause of troublesome breakdown of many mudrocks, it is essential to have reliable means of predicting this behaviour. Although the ISRM slake durability test is the standard...

Laboratory rock strength and slake durability tests show that while the two lithologies have similar tensile strengths before drying, the meander-supporting mudstone loses strength dramatically when dried and rewet (slakes), while the sandstone does not. The slaked mudstone bank rock was easily...

Examples of samples with varying degrees of abrasion resistance when subjected to the modified slake durability test. Photos A and B show a relatively non-resistant sample before (A) and after (B) testing, while photos C and D show a relatively resistant sample before (C) and after (D) testing. Note that more resistant rocks are likely scouring by quarrying and plucking and that the abrasion being simulated in the modified slake durability test is therefore not providing useful information on scour. This emphasizes the need to identify mode of scour in the field in order to specify appropriate laboratory testing.
