Effect of Molar Ratios and Curing Conditions on the Moisture Resistance of Magnesium Oxychloride Cement

Magnesium oxychloride cement (MOC) is a promising binder with many advantageous properties over traditional binders. Its main downfall, restricting large-scale use, its inherent susceptibility to moisture. However, in recent years, niche applications have developed where MOC has been deployed successfully. These include lightweight wall panels, floor tiles, and decorative panels. This paper investigates the effect of molar ratios (MgO/MgCl2 H2O/MgCl2) curing conditions on MOC. Findings illustrate that use appropriate implementation suitable regime can significantly improve moisture resistance After 28 days immersion water, samples lost between 40% 90% their strength depending ratio, demonstrating importance correct proportioning. It was also found at temperatures 20°C 50°C provides most stable humid conditions. findings add current knowledge available They will help end users performance work toward broadening range be used
