Fluorographene-doped magnesium oxychloride cement composites for construction
Original language description
In addition to excellent mechanical, physical and chemical parameters, magnesium oxychloride cement (MOC) composites offer numerous environmental benefits, particularly with regard to the necessary reduction of carbon dioxide emissions associated with the production of Portland cement based building materials. However, the limitation to the wider use of MOC is its low water resistance. Therefore, the possibility of improving the water resistance of magnesium oxychloride cement (MOC) composites by nano-adjustment using fluorographene (FG) was the subject of the research presented. A tannic acid (TA)-based surfactant was used to uniformly disperse the FG particles. The effect of FG added at the dosage of 0.2% and 0.5% by weight of the MOC binder in the MOC mixture was investigated and characterized by the assessment of the mechanical, basic structural and microstructural properties of the hardened composites. Particular attention was paid to the analysis of water resistance, for which the hygric parameters and the softening coefficient were measured after immersing the samples in water for 24 hours. The results obtained showed that FG in the amount of 0.2 wt% of the binder improved the water resistance, while 0.5 wt% of FG in the MOC binder gave results comparable to those of the reference sample. Since FG-doped MOC composites retained the excellent mechanical and structural parameters of MOC, the improvement in water resistance may enable them to more widely exploit their advanced properties and eco-efficiency in construction practice.
