| In this study, the use of a new polypropylene geofiber type called Microgrid Fiber (MGF) was investigated in comparison with a conventional Polypropylene Fiber (PPF) product. Uniaxial Compressive Strength (UCS), modulus of elasticity, ductility, and energy absorption capacities of Cement Stabilized Sand (CSS) mixes reinforced with different polypropylene type geofiber additives were investigated, carrying out a series of uniaxial deformability tests. According to the results, MGF-type fibers increased the strength and modulus of elasticity values at higher rates in comparison with the conventional PPF product. For the same fiber content, MGF-type new additive supplied up to 31% higher UCS values and 26% higher modulus elasticity values than those of the specimens with the conventional PPF additive. In addition, it was determined that MGF-type new fiber additives can supply better increases in ductility and Energy Absorption Capacity (EAC) properties of the CSS compared to the conventional PPF product. Rather than the conventional fiber, the novel MGF additives were assessed to be more effective for having proper adherence and soil reinforcement performances. | ||
