摘要：The morphological properties of the multi-walled carbon nanotubes (MWCNTs) reinforced Portland cement composites were investigated. MWCNTs with addition of up to 0.15 wt% of cement were incorporated to Portland cement with a water to cement ratio of 0.35. The porosity and pore size distribution of the composites were measured by mercury intrusion porosimetry (MIP), and the results indicate that the cement doped with MWCNTs obtained lower porosity and concentrated pore size distribution. The microstructure was analyzed by field emission scanning electron microscopy (FE SEM) and energy dispersive spectroscopy (EDS). It is shown that MWCNTs act as bridges and networks across cracks and voids.
