HPFRCC(High Performance Fiber Reinforced Cementitious Composite) is a class of FRCCs(Fiber Reinforced Cementitious Composites) that exhibit multiple cracking. Multiple cracking leads to improvement in properties such as ductility, toughness, fracture energy, strain hardening, strain capacity, and deformation capacity under tension, compression, and bending. These improves propeties of HPFRCCs have triggered unique and versatile structural applications, including damage reduction, damage tolerance, energy absorption, crack distribution, deformation compatibility, and delamination resistance. These mechanical properties of HPFRCCs become different from the kinds and shapes of used fiber, and it is known that the effective size of fiber
in macro crack is different from that in macro crack. This study is an experimental finding on the engineering properties of HPFRCCs reinforced with the PE fiber. Air content tests, table flow tests and uniaxial tensile test are carried out in order to compare with the engineering properties of HPFRCCs reinforced with matrix proportion and mixing method such as workability and toughness.
