Preparation and microstructural properties study on cement composites reinforced with multi-walled carbon nanotubes

In this research, multi-walled carbon nanotubes were used to delay the propagation and growth of cracks in cement mortar on the nanoscale. To improve the dispersion of multi-walled carbon nanotubes in the cement mix a polycarboxylate superplasticizer was used. The mechanical strength of multi-walled carbon nanotubes-cement nanocomposites mix containing 0.1–2% nanotubes by weight (wt) and 0.5% superplasticizer by (wt) was measured and compared...
