“…16, water vaporizes in the soil pores and is diffused from the interior of tiny pores to a larger pore extending upwards, being exposed to the specimen's top surface. With the gradual drying of the soil specimens, the water is vaporized at deeper depths in the soil, with the vapor passing through the dry surface layer to the atmosphere, which will, in turn, affect the interparticle tensile strength [5].…”

“…Primary crack generation and development depend on the soil's tensile strength and the tensile stress's magnitude [5,21]. As the significant primary cracks stabilize and secondary crack development begins, shrinkage of soil occurs, and soil particles get closer, resulting in the widening of the cracks.…”

Expansive soils shrink and swell, causing considerable density differences as the moisture content varies and cracks develop as the soil dries. This cracking condition has a detrimental effect on the stability of infrastructure built on expansive soil, such as road embankments. This paper investigates the influence of diatomaceous earth (at 5%, 10%, 15%, and 20% DE percent by mass) on the desiccation cracking of expansive soils. The report demonstrates an image analysis technique to describe soil surface cracking quantitatively. The geometric features of cracks, such as surface crack area and crack connectivity, were estimated and examined. The study considers soil crack area ratio and cracking index to investigate the effect of diatomaceous earth on expansive soil surface cracking. The crack area ratio and cracking index analysis results show that the expansive soil surface cracking is uneven and significant. The soil matrix containing 10% and 20% diatomaceous earth has reduced surface cracking and a homogenous radial cracking pattern. The image analysis approach, an essential method to quantitatively quantify soil desiccation cracking, revealed that diatomaceous earth substantially affects surface crack reduction.

“…To reduce the adverse effects of desiccation cracking on the engineering properties of fine-grained soils and improve soil strength and resistance, researchers have used field and experimental investigations to study the effects of adding fibers (i.e., polyester fiber [ 24 ], flax fiber [ 25 ], straw fiber [ 26 ], nylon fiber [ 27 ]), sugarcane pith [ 14 ], and microorganisms [ 28 ]) and other materials to strengthen the soil. The results indicate that the average length, width, spacing, and total area of soil cracks decrease obviously with the addition of fibers.…”

Desiccation cracking frequently occurs in mud, clay, and pavement. Understanding the evolution of desiccation cracking may facilitate the development of techniques to mitigate cracking and even prevent it from developing altogether. In this study, experimental investigations were performed focusing on the effects of fibers on the evolution of desiccation cracking in soil-cement. Varied types of fibers (i.e., jute fiber and polyvinyl alcohol fiber (PVA)) and fiber contents (i.e., 0%, 0.25%, 0.5%, and 1%) were involved. The digital image correlation (DIC) method was employed to capture the evolution and propagation of cracks in the soil-cement specimens when subjected to desiccation. The results show that the presence of fibers imposes significant effects on the crack propagation pattern as well as the area and length of the cracks in the soil-cement during shrinkage. The addition of fibers, however, insignificantly affects the evaporation rate of the specimens. The crack area and crack length of the specimens decreased significantly when more fibers were included. There were no macroscopic cracks observed in the specimens where the fiber content was 1%. The DIC method effectively helped to determine the evolution of displacement and strain field on the specimens’ surface during the drying process. The DIC method is therefore useful for crack monitoring.
