Carbon Nanotubes and Carbon Nanofibers for Enhancing the Mechanical Properties of Nanocomposite Cementitious Materials (2011, background): “…started testing discrete macro- to microfibers to control crack growth in cementitious materials (e.g., cement paste, cement grout, concrete) (Altoubat et al. 2009; Fischer and Li 2007; Li and Maalej 1996; Mangat et al. 1984; Ostertag et al. 2001; Savastano et al. 2005; Wang et al. 2008).”
Distribution of Carbon Nanofibers and Nanotubes in Cementitious Composites (2010, methodology): “while using polyacrylic acid polymers as a surfactant (10).”
Beneficial role of nanosilica in cement based materials – A review (2013, background): “The electrical resistance of the mix can also be reduced with the incorporation of CNTs and CNFs [33–44].”
Cement and Concrete Nanoscience and Nanotechnology (2010, background): “In some cases the MWCNT have been functionalized by the attachment of carboxylic acid groups to aid dispersion [65,66,68], but this approach has not been found to be necessary by all researchers.”
Surface-modified graphite nanomaterials for improved reinforcement efficiency in cementitious paste (2013, background): “PAA can effectively disperse graphite nanomaterials [79–81]; in addition, it can interact well with the cementitious matrix by forming different secondary and primary bonds with calcium silicate hydrate [3].”
Reinforcing effects of graphene oxide on portland cement paste (2015, result): “…Li et al. (2005) and Kumar et al. (2012), using much higher concentration of CNTs. Comparing the results achieved using polyacrylic acid polymer-treated multiwall CNTs (Cwirzen et al. 2008), a smaller concentration of GO is required to achieve a similar degree of increase in compressive strength.”
The influences of admixtures on the dispersion, workability, and strength of carbon nanotube-OPC paste mixtures (2012, methodology): “Although previous dispersion investigations have been undertaken on OPC–CNT-surfactant paste mixtures [16–20], none link the simultaneous need for aqueous dispersion of both CNTs and OPC particles; a key factor when considering future applications that involve future placement and fabrication of CNT”
On the aspect ratio effect of multi-walled carbon nanotube reinforcements on the mechanical properties of cementitious nanocomposites (2012, background): “Other researchers tried a novel approach by growing CNTs on the surface of the cement particles directly in order to enhance the dispersion and reduce the time and efforts of mixing and dispersing the CNTs within the cement paste [14,15].”
Nanotechnology in concrete – A review (2010, methodology): “Further work utilizing functionalization combined with ‘‘decoration” of MWCNTs with polyacrylic acid polymers [138] found improved dispersion, good workability, and increased compressive strength (nearly 50%) for loadings between 0.”
