Influence of Graphite Oxide Addition on the Properties of Magnesium Oxychloride Cement Composites
Original language description
Magnesium oxychloride cement (MOC) is as an eco-friendly construction material used in industrial as well as in residential applications thanks to its better performance in comparison with Portland cement (PC) considered. Magnesium oxychloride cement composites formed during the reaction between light-burned magnesium oxide powder and magnesium chloride solution, belong to non-hydraulic materials and offer the advantage of high early strength and low porosity. These performances could, however, be further improved by incorporating of selected nanomaterials. This paper therefore presents an experimental investigation of magnesium oxychloride cement paste with graphite oxide admixture. The chemical composition of raw light-burned magnesium oxide powder was analysed by X-Ray Fluorescence (XRF) and the morphology of graphite oxide was characterised using High Resolution Transmission Electron Microscopy (HR-TEM). Graphite oxide (GO) was added into the mixture in a concentration of 0.5 wt. %. Subsequently, the influence of GO on the properties of hardened MOC paste was analysed in terms of its bulk density, specific density, open porosity and compressive and flexural strength measurement. The characterisation of studied pastes using X-Ray Diffraction (XRD) and Scanning Electron Microscopy (SEM) analysis was done as well. It was found that the presence of GO significantly enhanced the flexural strength, decreased the open porosity and slightly improved the compressive strength compared to the plain MOC paste. The obtained results suggest that with the addition of graphite oxide to magnesium oxychloride cement, MOC-based nanocomposites intended for civil engineering can be developed. These are characterised by high strength and low porosity, which is particularly important for reduction of moisture related damage.
