Impact of Cement Type on the Mechanical Behavior ofFiber Treated Sand

In the present research, results of triaxial tests on fiber reinforced sand mixe with Portland cementhydrated lime and gypsum as cementing agents were compared. The cement content was 3% (dry wt.) of sand. Alsofibers 0.012 m in length and 23 μm thick were added at 0.0%, 0.5% and1.0% (dry wt.) of the sand cement mixtureSamples were prepared at 70% relative density. Samples with Portland cement and hydrated lime cured for 7 daysin humid room and constant temperature of 40 °C, respectively and samples cemented with gypsum cured for 24 hrin a constant temperature about 50 °C. Although, cement type influences energy absorption significantly inunreinforced sand, results of present study indicates the same energy absorption potential for hydrated lime and gypsum cemented fiber reinforced sand. The most energy absorption potential was recorded for the fiberreinforced soil cemented with Portland cement
