“…Previous studies by Moon and Beattie (1995), Erguler (2007), and Erguler and Ulusay (2009) also showed that rock materials break into fragments of varying sizes during the second cycle of the dynamic slake durability test, and that the fragments are much larger than the mesh of the drum. The large fragments that are retained in the drum are therefore classified as durable materials.…”

“…Although many rock types disintegrate following two cycles, they can still have high slake durability index values. Slaking behavior of various types of clay-bearing rocks under wettingdrying processes was studied by several researchers using the dynamic slake durability test (Moon and Beattie 1995;Gokceoglu 1997;Koncagul and Santi 1999;Gokceoglu et al 2000;Sadisun et al 2005;Fuenkajorn 2011;Sebastian Brysona et al 2012). …”

“…Although the dynamic slake durability test, recommended by ASTM and ISRM, indicates the susceptibility of a clay-bearing rock to slake and disintegrate, this test do not provide a reliable quantitative measure. Several studies have increased the number of slaking cycles (Taylor 1988; Moon and Beattie 1995;Gokceoglu ). An important limitation of the test is that the mesh is the same size (2 mm) in all of the drums used to evaluate the disintegration behavior.…”

Assessing the Behavior of Clay-Bearing Rocks Using Static and Dynamic Slaking Indices

Clay-bearing rocks are characterized by a wide variation in engineering properties and their resistance to short term weathering due to wetting and drying phenomenon. In this study, a research study was performed on different clay-bearing rocks selected from the Ilam and the Tajarak regions (Iran) to assess suitability of the static and dynamic standard slaking tests. Also in this paper, in order to estimate durability of the clay-bearing rocks, some physicalchemical properties were used in form of multiple linear regression analyses in relation to the static and dynamic slaking indices. The test results from the static and dynamic standard slaking tests showed that the materials retained in the 2 mm mesh drum consists of disintegrated particles varying in diameter from 2 to 25.4 mm. To achieve a more realistic evaluation of the disintegration properties of rock samples after each wetting-drying cycle, a sieve analysis approach is therefore more appropriate. Comparison of the multiple linear regressions between the slaking indices and physical-chemical properties showed that the disintegration ratio could characterize the durability behavior of the rock samples in both the static and dynamic states. Also, the results indicated that the static slaking index (I s ) was more acceptable for predicting the behavior of clay-bearing rocks than the dynamic durability index (I d ).

“…A major focus was on determining the applicability of the slake durability test. The slake durability test is used widely for evaluation of slaking behavior of rocks as a result of wettingdrying processes [7][8][9][10][11][12][13]. However, due to mechanical breaks occurring during the test, immersion of samples in water for only 10 min and the assumption that fragments larger than 2 mm are durable, the slake durability test has some limitations [14].…”

Veränderlich feste Gesteine sind sehr zerfallsempfindlich, da sie innerhalb kurzer Zeit u. a. durch Austrocknungs‐ und Wiederbefeuchtungs‐Wechsel ihren Zusammenhalt verlieren können. In einer umfangreichen Laborstudie wurde ein neues Verfahren zur Klassifikation der Veränderlichkeit entwickelt, mit dem eine eindeutige Erfassung des Zerfallspotenzials möglich ist. In der hier vorliegenden Studie wurde näher untersucht, welche Gesteinseigenschaften die Zerfallsneigung der Gesteine beeinflussen. Festgestellt wurde dabei, dass der natürliche Verwitterungszustand die Veränderlichkeit stark beeinflusst. Ursache hierfür ist ein mit der Verwitterung abnehmender Sulfatgehalt und ansteigender Interaggregatporenanteil.
