Experimental investigation on the contribution of pristine multi-walled carbon nanotubes (MWCNTs) addition to the strength enhancement of cement composites
The research discusses the different dosages of pristine carbon nanotubes that can be added for the strength enhancement of cement composites. Carbon nanotubes dispersion in the cement composite was aided using silica fume particles. Addition of silica fume was found to be helpful in strength increment by improving the bond between the nanotubes and cement matrix. The experimental results showed an increase in compressive strength up to 4.2% and 19% at 7 and 28 days testing for the CNTs dosages of 0.05%, 0.075% and 0.10% (by weight of binder) compared the reference specimen. This strength increment is due to improved microstructure formed by the addition of nanotubes.
