“…Straight-line approximation of the Mohr−Coulomb failure pattern shown in Figure S3 gave the angle of internal friction (Φ) to be 38.32°and 39.35°for dry and wet media, respectively, showing that the shear strength of prepared granular material is comparable to that of the Indian standard Ennore sand (in the range of 35−40°for Φ). 44 The elemental mapping shown in Figure 2E 1 −E 4 illustrates the uniform distribution of As(III) and As(V) over the surface of CMCFH composite upon adsorption.…”

Arsenicosis was recognized over 104 years ago. Elevated arsenic (As) concentrations in water is faced by about 200 million people worldwide and has become one of the biggest challenges in the context of water purification. Providing sustainable and affordable solutions to tackle this menace is a need of the hour. Adsorption on advanced materials is increasingly being recognized as a potential solution. Here, we report various functionalized microcellulose-reinforced 2-line ferrihydrite composites which show outstanding As(III) and As(V) adsorption capacities. Green synthesis of the composite yields granular media with high mechanical strength which show faster adsorption kinetics in a wide pH range, irrespective of the presence of other interfering ions in water. The composites and their interaction with As(III) and As(V) were studied by XRD, HRTEM, SEM, XPS, Raman, TG, and IR spectroscopy. Performance of the media in the form of cartridge reaffirms its utility for point-of-use water purification. We show that cellulose microstructures are more efficient than corresponding nanostructures for the purpose of arsenic remediation. We have also performed an evaluation of several sustainability metrics to understand the “greenness” of the composite and its manufacturing process.

“…Cicek et al [19] investigated the influence of the first reinforcement layer depth through indoor plate load test and finite element model analysis, and the effective depth of the first reinforcement layer is obtained. Ghosh and Bera [20] investigated the effect of the geotextile ties on the uplift capacity of anchors embedded in sand. Boushehrian et al [21] conducted a numerical study on the load-carrying behavior of the soil reinforced with geogrid and grid-anchor under cyclic loading.…”

In order to analyze the uplift bearing capacity of transmission tower foundation in the geosythetic-reinforced aeolian sand, a series of simplified indoor modeling tests are carried out. A simplified reduced-scale foundation made according to the prototype and the uplift bearing capacity of transmission tower foundation in geosynthetic-reinforced aeolian sand is studied. Three kinds of reinforcement materials are embedded in the sand according to five ways of layout spacing. A total of 15 reinforcement schemes are tested. The results show that ultimate uplift bearing capacity of transmission tower foundation can be significantly improved by the reinforcement treatment of geotechnical materials in the aeolian sand. The type and spacing of reinforced materials also have a significant influence on the uplift bearing capacity of the foundation model in reinforced aeolian sand, and the effect of reinforcement works until the end of the loading process. The comprehensive effect is evaluated by the ratio of bearing capacity improvement and the total layer of reinforced materials. Based on the above results, the bearing mechanism of transmission tower foundation in geosynthetic-reinforced aeolian sand is elaborated and analyzed in detail.

“…Belled anchor piles may be attractive and economy-friendly alternative to resist resultant pull-out forces in foundation design, but its uplift capacity has yet not been fully investigated. e uplift capacity is influenced by embedment depths, sizes of diameter, and bell angles as observed by Dickin et al [2][3][4][5][6][7][8], but these studies are carried out on homogeneous sand only. Few field tests on belled anchors were reported by Adams and Radhakrishna [9] and Ismael and Kylm [10].…”

This experimental study explains the contribution of embedment ratios, diameter ratios, and bell angles to uplift capacities of single-belled anchors and formation of nonlinear failure surfaces in homogeneous and layered sand deposits. Uplift capacities in both types of sand deposits are increased with higher embedment ratios, lesser diameter ratios, and bell angles. Uplift capacities are higher in layered sand deposit in comparison with homogeneous sand deposit for the same model. Analytical uplift capacities are predicted by the horizontal slice method based on observed failure surfaces. A comparative discussion is made on nonlinear failure surfaces as well as analytical uplift capacities in reference to aforementioned parameters for the variation in sand deposits. The 45° and 63° belled anchors are more effective as uplift-resistant structures than 72° anchors in both types of sand deposits. Out of 36 analytical data on homogeneous sand and 33 analytical data on layered sand, 94.45% data are within the range of +08.51 to −10.70% and 100% data are within the range of +10.47 to −10.72%, respectively, with respect to the experimental uplift capacities. Four numbers of multiple linear regression models have been developed by observed breakout factors to eliminate the size effect, so the newly developed models are suitable for actual engineering to compare with prototype tests within the suggested imitation of values of variable parameters.
