Analysis of Portland cement consumption reduction by using functionalized multiwalled carbon nanotubes in mortars
Abstract The use of carbon nanotubes in cementitious materials improves the mechanical properties of these composites and increases their compressive and flexural strength. The main objective of this study was to evaluate the technical feasibility of reducing the Portland cement content by using fu...

| description | Abstract The use of carbon nanotubes in cementitious materials improves the mechanical properties of these composites and increases their compressive and flexural strength. The main objective of this study was to evaluate the technical feasibility of reducing the Portland cement content by using functionalized multi-walled carbon nanotubes (MWCNT) in mortar samples, using mechanical properties as parameters (compressive strength, flexural strength and modulus of elasticity). Experimental results allowed us to conclude that the addition of MWCNT in 0.1% by weight of Portland cement, to the mortar samples allowed a reduction of the Portland cement content by up to 10%, while the water/cement ratio remained unchanged without affecting the mechanical behavior. |
