“…The slake durability index experiment is used to capture the durability of the weak rocks (Admassu et al 2016). Test method in this present study is described as follows, and all of the samples were subjected to dry to constant weight in an oven at 105 °C before the test.…”

“…08, the slake durability index test is tumbling 10 pieces of rocks each weighing forty-sixty gram for double ten minutes drying-wetting cycles in a water submerged mesh drum (2 mm mesh size) (Admassu et al 2016; American Society 1824). So, each group of the experiment contains 10 pieces of rocks in this test.…”

“…The slake durability index test is the recommended measurement method by ASTM D4644-08. But, due to the fact that fragments of material retained in the test drum can be larger than 2 mm making the slake durability index test inadequate to quantify durability of rocks (Admassu et al 2016), the application of this model is limited. The widely used model to evaluate the disintegration properties is the fractal model, which was used in (Zhao et al 2007;Su et al 2005;Zhao et al 2018;Zhao et al 2003).…”

“…Furthermore, Erguler and Shakoor (Erguler and Shakoor 2009) proposed a new method and referred to as the disintegration ratio. Admassu et al (Admassu et al 2016) employed multivariate statistical method to re-evaluate the slake durability index test. Moradian, Ghazvinian, Ahmadi and Behnia (Moradian et al 2010) proposed the predicting method of the slake durability index using indirect tests.…”

The disintegration of soft rock in water is an important cause of engineering disasters, and the research on the disintegration characteristics is also of great significance for the design and production practice of major projects. Considering this, a series of slake durability experiments were conducted to explore the disintegration behaviours of red sandstone under cyclic drying-wetting cycles, and the Soil Mechanics' theory was introduced to investigate these artificial weathering of red sandstone. Then, based on the analyzing of the grain size distribution, the predicting model of the disintegration breakage of red sandstone through Weibull distribution was established. In addition, the proposed model was compared with the widely used fractal model to illustrate the advantage of established model. The physical significance of the parameters was captured. Moreover, the disintegration behaviours of red sandstone were quantified by the newly derived and traditional disintegration ratio. The updated expressions of gradation indicators (i.e., C u and C c Þ of unified soil classification were acquired based on the proposed model.

“…extensively in the literature in order to determine the durability of the rocks, especially weak and clay bearing rocks. The studies of Erguler and Ulusay (2009), Admassu et al (2016) and Gratchev and Kim (2016) can be given as examples of this kind of studies. In the study of Erguler and Ulusay, SDI tests were carried out on the samples collected from the various regions of Turkey, and also, a new test (Disintegration Index test) and a new classification system based on the results of new test were suggested.…”

Slake Durability Index test is being widely used to determine the disintegration characteristics of the weak rocks when they are subjected to drying and wetting cycles. In the test standards, samples are recommended to have rounded or close to spherical shape. In this study, a new method called as Pasha Method was proposed and applied to prepare equal-sized spherical samples. Slake Durability Index tests were performed on the spherical and rounded sample sets prepared from different rock types. According to Slake Durability Index test results in all rocks, the difference between the first cycle and second cycle results of the rounded samples and the spherical samples is found as 0.05-8.04% and 0.1-13.63%, respectively. When only the spherical test results were considered, the difference in the first cycle and second cycle values is found to be 0.28-2.19% and 0.44-7.57%, respectively. Applying this new method allows researchers to perform this test on equal-sized spherical samples, resulting in the minimization of the shape effect on the test results.
