Case study on nanoscale modification of MOC-based construction composites: Introduction of molybdenum disulfide
Original language description
The excellent technical parameters of magnesium oxychloride cement (MOC) and its ability to sequester CO2 from the environment predestine its use as an alternative to Portland cement. However, its main shortcomings, low water resistance, and excessive water absorption need to be addressed to enable its wider application in construction. For this reason, the improvement of the water resistance of MOC-based composites through the use of nanosized molybdenum disulfide (MoS2) is the subject of this case study. The MOC-based composites were subjected to experimental testing of their chemical, structural and physical parameters using a wide range of advanced laboratory techniques. The composites enriched by MoS2 nanoadditive exhibited a densified and compact structure with improved mechanical parameters and stiffness. Water transport and storage were significantly decelerated and reduced by the incorporation of MoS2 nanoparticles, resulting in an improvement of water resistance, characterized by the softening coefficient, which was 66.1 % after 24 h of immersion in water, which is about 13.8 % higher than that of the reference MOC-based composite. © 2023 The Authors
