Increasing the Resistance of Chloromagnesian Composites to Cracking Under Prolonged Water Saturation
This article presents the results of a study devoted to determining the effect of sodium tripolyphosphate (STPP) additives on the properties of magnesium chloride composites, in particular, on their resistance to long-term water saturation. Magnesium oxychloride cements (MOC), especially based on dolomites, are highly prone to cracking when exposed to water for a long time. This effect depends on the degree of crystallization of the main active component—magnesium oxide, which is part of their composition. With an improper degree of crystallization, an artificial stone is formed, which individual phases are capable of creating internal stresses leading to destruction during long water saturation. In this paper, we consider the ability of the STPP modifier to stabilize these phases, as well as its effect on some physical and mechanical properties of chlorine magnesia composites. During the research, methods of mathematical planning of the experiment, standard methods for studying strength characteristics and water absorption by weight were used. It has been shown that the introduction of STPP additive reduces the strength of composites, but contributes to an increase in their resistance to cracking during prolonged water saturation.
