The article contains the results of a three-factor experiment. The dependence between the compressive strength, hygroscopic, and the composition ratio of magnesium oxychloride cement was obtained. The ratio between the main components of magnesium oxychloride: magnesium oxide, magnesium chloride and water were used as factors instead of the density of the sealer and its quantity. The values of the responses were received empirically. Statistical analysis of actual data allowed to obtain the mathematical model of properties. Check of adequacy of mathematical models showed that the actual values of strength and water absorption correlate well with the calculated values. This allows assigning compositions of magnesium oxychloride cement of various kinds of magnesia with desired properties and avoiding the formation of efflorescence and cracking of magnesia materials. The content of magnesium oxide in magnesia, required strength and hygroscopic must be the initial data.
Keywords: magnesia astringent; bischofite; strength; hygroscopic.
