“…Regarding the 0.5% fiber mixture, the maximum dry density rises. This can be attributed to a better packing configuration since the low content of fibers and smaller soil particles fill the voids generated in the mixture, which was observed in other investigations with fiber used in the soil [48], as observed in Figure 5.…”

“…Fiber length is an important factor in ρ d behavior; it is evident that, for each percentage of fiber, as its length increases, a decrease in ρ d occurs in most cases, except for the 0.5% fiber mixture, where the maximum dry density rises. This can be attributed to a better packing configuration since the fibers and smaller soil particles fill the voids generated in the mixture, which has been observed in other investigations with fibers used in soil [48].…”

The present investigation determines the influence of abaca (Musa textilis) fiber inclusion on the simple compressive strength of reconstituted sandy silt specimens. For this purpose, fibers of different lengths (5, 10 and 15 mm) and quantities (0.5, 1.0, 1.5 and 2.0% of soil dry weight) are added to produce the reconstituted specimens. Subsequently, the physical and mechanical behavior of soil–fiber mixtures were evaluated through compaction and unconfined compression tests. The experimental results showed that increases in fiber content or length, or both, led to a 1235.1% increase in maximum compression stress (compared to the fiber-free soil). Compression failure occurred at a greater axial strain when 10 and 15 mm fibers were added at 1% dosage or in percentages equal to or greater than 1.5% regardless of fiber length. A series of linear mixed models identified statistically significant effects of fiber length and percentage on the level of effort and on the unitary deformation.
