TL;DR: In this paper, a comparison was made between the performance of unreinforced slope, high-density polyethylene geocell retaining wall and coir geocell wall to evaluate the potential of coir over synthetic geocell as reinforcement, and the roughness and absence of perforations in coir material resisted the movement and failure of the wall for a longer span.
Abstract: In the present study, coir is used to fabricate geocells and to construct model retaining walls for application in sloppy regions to retain the soil. The performance of coir geocells under dry and wet conditions during rainfall were evaluated by conducting laboratory model tests. The study presents horizontal and vertical deformation against surcharge load for different scenarios of reinforcement using geocells. A comparison was made between the performance of unreinforced slope, high-density polyethylene geocell retaining wall and coir geocell retaining wall to evaluate the potential of coir geocell over synthetic geocell as reinforcement. The roughness and absence of perforations in coir material resisted the movement and failure of the wall for a longer span. The horizontal displacement was more for coir geocell retaining wall compared to wall made of high density polyethylene (HDPE) geocells. This may be due to the interlocking effect in coir HDPE geocell as perforations provide contact between the sand particles. The inexpensive and easily disposable coir can be effectively used as reinforcement in the construction of a retaining wall.

TL;DR: In this article, the results of model footing tests on sand bed reinforced with HDPE and coir geocells were presented, and the potential of sand tire crumb (STC) mixture as infill material is evaluated in the study in comparison with pure sand.
Abstract: This paper presents the results of model footing tests on sand bed reinforced with HDPE and coir geocells. The infill material influences the performance of geocells. The potential of sand tire crumb (STC) mixture as infill material is evaluated in the study in comparison with pure sand as infill materials. To select the appropriate blend of sand and tire crumb, the shear properties and density properties were analyzed by performing direct shear and density tests. The mix which has shown the highest shear strength and density properties has been selected, and plate load tests were carried to analyze the mechanism and effectiveness of tire crumb as infill material in geocell pockets. From the results, it is clear that the sand tire crumb mix is effective as infill materials, especially for coir geocells. The surface heave was found to reduce significantly with sand tire crumb mix as infill material.

TL;DR: In this paper, a series of laboratory model tests have been carried out to investigate the using of shredded waste tires as reinforcement to increase the bearing capacity of soil, and it was shown that increasing of shred content increases the BCR, however, an optimum value for shred content is observed after increasing shreds led to decrease in BCR.

TL;DR: In this article, the effect of the geocells as a major material in retaining structures and the failure mechanism of the said structures under surcharge was examined on nine model geocell retaining walls, where the main variables in the tests include the height and the facing angle of the structure, the type of surcharge, and the reinforcement embedded in the two types of externally stabilized structures.
