The clay mineral bentonite has received a lot of attention for its potential to reduce the harmful effects of drought on soil health and biological activity. Reduced enzymatic activity and microbial diversity are two negative outcomes of the drought’s impact on soil quality. Bentonite, however, has been shown to aid in the restoration of biological functions in drought-affected soils. Bentonite’s function as a soil moisture retainer is an important consideration. Bentonite acts as a reservoir, trapping water within its layers due to its high water-holding capacity and ability to form a gel-like structure. This capacity for water retention can reduce the negative impact of drought on soil organisms, making conditions better for enzyme activity and microbial life. Bentonite has also been shown to increase soil enzyme production and activity. Soil fertility and healthy ecosystems rely on the work of enzymes in nutrient cycling and organic matter decomposition. Reduced enzymatic activity is a common consequence of drought stress, which in turn reduces nutrient availability and worsens soil health. The application of bentonite, however, has been shown to increase enzyme production and activity even in drought conditions. This has the potential to improve soil health and productivity by preserving vital soil processes and encouraging nutrient cycling. In addition, bentonite can increase soil microorganism activity in dry areas. Soil microorganisms play a crucial role in the cycling of nutrients, the control of disease, and the health of the soil ecosystem as a whole. Reduced microbial diversity and activity have been linked to drought stress. However, research shows that applying bentonite to drought-affected soils increases both microbial growth and diversity. Increased nutrient availability, enhanced soil structure, and enhanced water infiltration and retention are all possible results of microbial stimulation. In conclusion, areas that have experienced drought can benefit from bentonite’s ability to improve soil enzymes and biological activity. Bentonite helps restore and maintain soil health even when water supplies are low. It does this by increasing water retention, encouraging enzyme production, and boosting microbial activity. To fully realize bentonite’s potential for fostering sustainable agriculture and sustaining healthy ecosystems, more study is required to determine the optimum application rates and methods.

“…The experimental results showed that the mechanical characteristics was improved with the addition of polypropylene fibers. Hussein and Ali (2019) studied the effect of adding polypropylene fiber on the behavior of expansive soil. In this study Unconfined Compression Test, One-Dimensional Consolidation Test, Swelling Test, Sieve Analysis and Cycle Swell Shrink Test were carried out and test results were saved.…”

In recent years, the use of natural and synthetic fibers in soil improvement has become widespread in soil mechanics applications. Easy to use and low cost fibers have been the subject of many geotechnical researches in recent years. In this study, results of previous mechanical experiments performed on fiber-cohesive soil mixtures were reviewed in a systematical approach. Based on the data derived from the experimental studies available in the literature, it has been observed that various soil properties including soil strength have improved with increasing density of the fibers up to a certain level. The percentage of added fiber has a significant effect on improving soil properties. Based on statistical analysis, simple correlation relationships were suggested based on the investigated test database.

“…and (2) chemical stabilization (by adding materials such as fly ash, salts, cement, lime, etc.). Recently, the addition of synthetic fibers [5][6][7][8][9][10][11][12][13] and natural fibers [13][14][15][16][17][18][19] has been considered among effective soil improvement techniques. Many studies have shown that the use of fibers (of natural or synthetic origin) gives satisfying results regarding the expansive behavior of soils [1-4, 8, 9, 12-14].…”

Effect of Polypropylene Fibers on Swelling Potential and Shear Strength of Clay

Expansive clays can cause major problems for urban development (roads, railways, infrastructure, etc.); therefore, reducing the swelling potential of clays has always been a concern in the geotechnical field. The presented paper investigates the effect of polypropylene reinforcement fibers on the swelling potential and shear strength of clay. The samples studied were taken from the clayey region of Mila, located in the northern east of Algeria. The experimental procedure adopted in this research consists first of the assessment of the physical, mechanical, and mineralogical characteristics of the soil samples without reinforcement. Then, swelling pressure, swelling rate, and swelling index are used to assess the swelling potential of these samples. After the reinforcement using a variety of polypropylene fiber concentrations (2 to 6% of the weight of the dry clay), the free swelling is clearly reduced. The optimum reinforcement rate in this case is 4%, in which the swelling was reduced by 90.7%. Finally, to offer more insights regarding the impact of clay reinforcement using polypropylene fibers, the effect of this later on the mechanical properties of the studied clay was also analyzed through the tangential shear strength. It was found that the polypropylene fibers increased the tangential shear resistance of Mila’s clay. Doi: 10.28991/CEJ-2023-09-03-04 Full Text: PDF
