AbstractAbout the AuthorReferences
Results of the study of the structure formation process when hardening a new waterresistant hydraulic magnesium substance – a hydrocarbonate magnesium binder – are presented. Improvement of the water resistance and giving hydraulic properties to the magnesium cement is connected with the use of a principally new gauging liquid – magnesium bicarbonate. The use of this solution allows hardening of a magnesium composition not only in the air but also in water. The waterresistance coefficient which corresponds to the coefficient of hydration hardening is up to 3.6. When gauging magnesium binders with the water solution of magnesium bicarbonate, main products of hardening are magnesium hydroxide and mag nesium hydrocarbonates, Magnesium hydrocarbonates are insoluble in water that provides the improved water resistance of magnesium compositions and the possibility of their hard ening and maturing in water.
