    Abstract

    In order to study the influence of calcium carbonate whisker with different content on the mechanical properties and microstructure of polyethylene fiber reinforced cement-based composite(PE-ECC), four groups of PE-ECC specimens with different content of calcium carbonate whisker were designed, and the compressive properties, tensile properties and three-point bending fracture properties were tested on them. The microstructure was studied by XRD, SEM and NMR. The results show that calcium carbonate whisker can strengthen and toughen PE-ECC. With the increase of calcium carbonate whisker content, the strengthening and toughening effects first increase and then decrease. When the content of calcium carbonate whisker is 1% (volume fraction), the compressive properties, tensile properties and fracture properties of PE-ECC are improved best. Appropriate amount of calcium carbonate whisker can fill the matrix, reduce the number of less and more damaged pores, and improve pore structure.
