HIGH-PERFORMANCE MOC COMPOSITE DOPED WITH CARBON-BASED NANOADDITIVE
Abstract
Magnesium oxychloride cement (MOC) is a non-hydraulic binder produced in a more eco-efficient way than Portland cement and due to its favorable properties represents its promising alternative in the production of construction materials for specific applications. The specific advantage of MOC is the fact that it can accommodate organic as well as inorganic substances in the form of fillers, aggregates, additives, reinforcement, etc. which enables enriching properties and performance of the final composite material. In this paper, the development and experimental testing of the highperformance composite based on MOC doped with graphene nanoplatelets is the subject of the presented research. The effect of graphene on the final properties and parameters of the hardened composite paste was evaluated using several analytical methods comprising SEM and XRD analyses, mechanical parameters testing, assessment of micro- and macro-structural parameters, and determination of physical parameters of composite, such as hygric and thermal properties. The developed composite was characterized by extremely low porosity, excellent mechanical strength and stiffness, low water absorption, and high thermal conductivity and volumetric heat capacity which were significantly enhanced by the use of graphene nanoplatelets. The acquired results represent a promising route how to effectively improve the reactive magnesia-based composites using carbon nanoadditives.
