Efficacy of Resinous Polypropylene (PP) Fibers on Strength Behavior of Reinforced Soils

Abstract:

In the current study, Laboratory uniaxial compression tests are carried out in order to determine the strength and mechanical behavior of silty sand reinforced with randomly distributed short resinous Polypropylene (PP) fibers. The stress-strain behavior of composite materials is investigated through varying the number and length of PP fibers. In order to study the effects of the length and weight percent of fibers on the results of the uniaxial compressive strength, tests were accomplished on specimens with three different lengths and weight percentages of fibers. The results demonstrate increasing weight percent of fibers, in a constant length, leads to increase the maximum strength. Meanwhile, increasing the length of fibers, in a constant weight percent, reduces the maximum strength. Moisture absorbency of fibers which was about 120% at first, however, could be reduced to just 9% by using the epoxy polyamide resin. Moreover, the resin causes more interaction between sand aggregates and fibers leading to a higher internal friction angle.
