Experimental Volume Incidence Study and the Relationship of Polypropylene Macrofiber Slenderness to the Mechanical Strengths of Fiber-Reinforced Concretes

An experimental study was conducted to examine the mechanical strengths of concretes with straight high-strength knurled polypropylene macrofibers. Incidences concrete were determined for three different fiber dosages and lengths. In addition, compressive, indirect-splitting-test tensile, flexural through testing. The results showed no statistically significant correlation between volume length fibers compressive strength fiber-reinforced (PPFRC). However, there a split tensile strength, volume, when greater than 0.80%, 50 mm. Furthermore, modulus rupture increased 0.80% 60 Finally, equations proposed determine by test as function mixture’s resistance without fibers, fibers’ length.
