Mechanical Properties of Nanocomposite Cement Incorporating Surface-Treated and Untreated Carbon Nanotubes and Carbon Nanofibers (2012, background): “Previous work (Tyson et al. 2011; Yazdanbakhsh et al. 2009) has shown that a commercial superplasticizer, a high-range polycarboxylate-based, water-reducing ADVA Cast 575 admixture from Grace Corporation, works well to disperse the nanofilaments with minimal effect on the hydration time of the cemen”
Reinforcing effects of graphene oxide on portland cement paste (2015, result): “…(Li et al. 2005; Konsta-Gdoutos et al. 2010a), Young’s modulus (Saez de Ibarra et al. 2006; Konsta-Gdoutos et al. 2010a), and fracture toughness (Tyson et al. 2011) have been reported, although some contradictory results have been reported, which are generally attributed to poor dispersion of…”
Surface-modified graphite nanomaterials for improved reinforcement efficiency in cementitious paste (2013, background): “Recent investigations have also demonstrated the value of carbon nanomaterials [16–32] in cementitious matrices.”
On the aspect ratio effect of multi-walled carbon nanotube reinforcements on the mechanical properties of cementitious nanocomposites (2012, methodology): “[7–9,20]) have investigated the integration (dispersion and bond) of both CNTs and carbon nanofibers (CNFs) of different concentrations within the cement paste at different ages.”
Characterization of alkali activated geopolymer mortar doped with MWCNT (2015, background): “Adequate dispersion of CNTs in cement is challenging as van der Waals forces are responsible for their bundling and agglomeration even at very low concentrations, thereby limiting their potential benefits (Chen et al. 2011; Tyson et al. 2011; Gao et al. 2009).”
