The Influence of 1D and 2D Carbon Nanomaterials on Properties of Magnesium Oxychloride Cement Mortars
Original language description
In this study, magnesium oxychloride cement (MOC) mortars reinforced with multi-walled carbon nanotubes (MWCNT) and graphene were prepared and analyzed. The lower CO2 footprint of MOC in comparison with the production of ordinary Portland cement (OPC) predestines MOC-based materials to be an environmentally sustainable alternative to OPC. However, the wider spread of MOC is hindered by its low water resistance. The combined influence of MWCNT and graphene as 1D and 2D carbon nanomaterials on properties of MOC mortars was experimentally studied in terms of basic physical, microstructural and mechanical parameters assessment. Moreover, the water resistance was investigated in detail based on the measurement of hygric parameters and softening coefficient after 24 h exposure to water. The addition of nanomaterials was (0.25+0.25) wt.% and (0.5+0.5) wt.% of MOC binder. The results showed that the combined addition of 1D and 2D carbon nanomaterials led to a reduction in average pore diameter, and thus quite obvious improvement in water resistance compared to the control MOC mortar. The developed nano-doped MOC mortars appear to be perspective materials that might find application in the construction industry.
