“…Shapes of the specimens have an impact on degradation due to different mechanisms in the slaking processes. In particular, irregular shapes tends to give lower index values, when compared to specimens that had rounded shapes [10][11][12]. The weathering process is very slow it takes hundreds or thousands of years.…”

Mining operations deal mainly with hard and soft rocks with different mechanical properties and varying strengths. The aim of the slake durability test is to present an index related to degradation resistance of rock when exposed to standard cycles of wetting and drying. Research in geology and rock mechanics is done to explain the influence of the rock index properties in determining the strength, durability and pulse velocity of the rock. This paper enlightens the prediction of the rock’s behavior and nature of the degradation of rocks The index values obtained for sandstone are varying from 97.36 to 99.04% and for shale it ranges from 10.21 to 14.06%. The slake durability index test for sandstone sample indicates that it is high durable and the shale indicates very low durability. The average value of uniaxial compressive strength was calculated to be 83.144 MPa.

“…Considering that the disintegration of soft rock has suffered a large number of cyclic drying and wetting in the natural environment, many investigations have studied the disintegration characteristic of soft rock under the action of cyclic drying and wetting. Ankara et al (Ankara et al 2015) compared the slake durability index values of different specimen after second, fourth and twelfth drying and wetting cycles, and higher index values were captured from the sphere specimen when compared to rounded sample results. Zhao, Lu, Deng and Liu (Zhao et al 2018) studied the effect of acid environment on the disintegration characteristic of soft rock through 24 cycles of drying and wetting.…”

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.

Cement stabilization is a practical improvement method of the soil bearing capacity of problematic soils. Soil bearing capacity is attributed to its strength and durability. The decrease in durability can be caused by weathering. On this account, to improve the long-term behavior of soil experiencing weathering process, it is necessary to apply cement stabilization to ensure the quality of road performance. This paper presents the results of a laboratory investigation on slaking index and the physical change of cementstabilized soil. A new sample preparation method of stabilized soil is presented in this study for the slakedurability test. The cement content was varied from 2 to 10 percent of the dry soil. The test results show that the unstabilized compacted-siltstone was ruined on the first test cycle. In general, the degree of slaking (Is) increases with the slaking cycle but decreases with the cement content. Whereas, the slaking durability index (Id(2)) increases as cement content increases. A large quantity of cement was required to obtain a successful stabilization. This study recommends that 7% of cement is suitable for soil modification, while 10% of cement satisfies the requirement for stabilization.
