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.关键词
