To conduct a comparative analysis of the impacts nanosilica (NS) and carbon nanotubes (CNTs) on mechanical properties polyethylene fiber-reinforced cementitious composites, seven groups ECC specimens with different nanomaterial contents were prepared. The uniaxial compression tensile tests conducted, mineral composition was analyzed via X-ray diffraction, microstructure examined using scanning electron microscope. results show that both types nanomaterials can effectively enhance ECC. Meanwhile, characteristics exhibit pattern initial increase followed by decrease as content rises. NS exhibited superior performance in augmenting compressive strength early crack ECC; however, CNTs more effective enhancing peak strain difference between enhancement not significant. consume CH crystals to generate C-S-H gels make matrix material dense, improve transition zone at fibre-gel interface While bridge inhibit extension micron scale, form fibre mesh structure PE fibres for stress transfer, deformation capacity macroscopic scale.
