Mechanical Properties and Impermeability of High Performance Cementitious Composite Reinforced with Polyethylene Fibers

In view of the delicate demands of materials for engineered cementitious composites (ECC), this paper presents a simple new brand of high performance cementitious composite (HPCC) prepared with polyethylene (PE) fibers (HPCC-PE). PE and steel fibers were employed to prepare fiber reinforced cementitious composite (FRCC), respectively, in order to perform comparative analysis. The experimental results show that the addition of fibers improves flexural deformation capacity as well as impermeability. A high flexural deflection capacity, which is almost 160 times of that of conventional concrete, was achieved for HPCC-PE accompanied by multiple cracking on the bottoms of the beams at the pure bending region. Scanning electron microscope (SEM) observation reveals that the fibers in HPCC-PE can still carry loads and slip inside the fiber tunnel in spite of the abrasion damage on the periphery caused by the matrix.The low chemical bond of PE fibers with surrounding cementitious matrix increases the potential of achieving saturated multiple cracking.
