Macro-Mechanical and Micro-Mechanical Properties of Nano-Enhanced Magnesium Oxychloride Cement
Original language description
This study is focused on influence of graphene nanoplatelets as additive in magnesium oxychloride cement (MOC) paste. This material composed of light-burned magnesia, prepared at lower temperatures than ordinary Portland cement (PC), is considered as its eco-efficient low-carbon alternative with properties comparable to high performance concrete such as high mechanical resistance, stiffness, and low porosity. Two composite pastes were prepared, reference paste and paste enhanced with graphene, and subjected to several testing methods. Among the used analytical techniques, scanning electron microscopy, energy dispersive spectroscopy and tests for assessment structural characteristics, macro-mechanical parameters, and micro-mechanical properties using nanoindentation apparatus were applied. While the results of control sample show excellent performance on its own, the doping MOC paste with graphene nanoplatelets further enhanced composite characteristics in terms of high compactness, mechanical resistance, and hardness. It was concluded that graphene-enhanced magnesia-based composite possesses high mechanical resistance which is crucial for its presumed application in building industry as load-bearing construction material.
