Exploring mechanical performance of hybrid MWCNT and GNMP reinforced cementitious composites
Abstract
Nano-engineered cement composites using a hybrid of multiwalled carbon nanotubes (MWCNTs) and graphite nano-micro particles (GNMPs) integrates the superior mechanical performance of MWCNTs and the better dispersibility and shielding capability of GNMPs. Combinations of MWCNTs and GNMPs at total of 0.08% over cement weight were ultrasonically dispersed in aqueous solution to make the cement mortar. The results show that incorporation of graphite platelets can synergistically improve the dispersion and compatibility of MWCNTs with surrounding cementitious matrix. Furthermore, the incorporation of 2-dimenstional GNMPs provided better resistance against water absorption and external sulphate attack. We assert that by limiting the hybridization of MWCNTs and GNMPs to a ratio of 1:0.125 (C1G0.125), a cementitious composite with enhanced mechanical performance can be developed. Young's modulus, flexural strength and flexural toughness was improved by 87%, 61%, and 51% respectively. Furthermore, the findings of this study provide the new insights on the design of hybrid nano reinforced cement composites with improved mechanical properties for various applications.
