Abstract

Abstract

Through shear tests on 12 polyethylene fiber-reinforced engineered cementitious composite (PE-ECC) V-notched beams, the effects of different mix proportion and fiber content on the shear performance of V-notched PE-ECC beams were studied. The test results showed that the V-notched beam with pure matrix was obvious brittle damage, while the V-notched PE-ECC beam was ductile damage. The cracks of the V-notched PE-ECC beams mainly appeared in the region between the loading point and the support on both sides of the notch, and the V-notched PE-ECC beams exhibited multi-cracking characteristics. When the load reached the peak load, the specimen shows the main crack and the specimen had obvious deflection. When the fiber content is in the range of 0%-2%, the shear capacity and ductility of V-notched PE-ECC beams increased with the increase of fiber content, and the crack propagation of the specimens with 2% fiber content was more sufficient than that of the specimens with 1% fiber content, while the average shear strength of PE-ECC was 9.46 MPa, which was 1.79 times of the axial tensile strength, when the fiber content is 2%.
