Properties of Hybrid Fiber Reinforced Cement Mortars as a Function of Type of Fiber

Eight hybrid fiber reinforced cement mortar (HFRC) mixes reinforced with Garnet-Nylon, Polypropylene (PP), Steel Fiber (SF) was tested in order to examine the effect of the W/B and replacement ratio of the Garnet-Nylon, PP, SF on the properties of matter and different material properties of HFRC. Main variables investigated were W/B and replacement ratio of the Garnet and Nylon, PP, SF. The measured material properties of fiber reinforced NS (Nylon-SF) specimens were analyzed using the two types of strength and compared with those recorded with PS (PP-SF) specimens. The flow of HFRC increased with the increase of the W/B. In addition, compressive strength, bending of HFRC was higher than those of replacement ratio of the Garnet-fibers, though the total HFRC was lower than that with NS-GA-01 specimen. For enhancing the toughness and strength of HFRC, using the GA of 5 % and Nylon of 0.1 %, PP of 0.1%, SF of 0.4% replacement ratio was more effective than using the GA of 20 % and Nylon of 0.4 %, PP of 0.4%, SF of 0.8% replacement ratio.
