Abstract:
To obtain the tensile properties of plant fiber-reinforced cementitious composites (PFRC). In this paper, the axial tensile numerical simulation and test study of PFRC panels with four thicknesses are carried out, and their tensile properties are analyzed and studied, which provides the relevant basis for the engineering application of PFRC panels. The results show that the peak load of uniaxial tensile failure of PFRC panels with thicknesses of 8mm, 12mm, 15mm, and 18mm is 424N, 664.8N, 825N, and 986.4N respectively. With the increase of the thickness of the PFRC panel, its bearing capacity is gradually increasing, and its peak tensile strain is about 0.028 %, which is 1.83-2.75 times that of ordinary concrete, and the tensile strength is about 2.73 MPa. It is proved that the addition of plant fiber can increase the toughness of the cement matrix, and the increase of PFRC panel thickness can improve its tensile bearing capacity, but does not affect its tensile strength.
