Annotation: An effect of heating an alkaline silica-alumina and magnesia binder stone on the basis of soluble silicates and sodium aluminate at 110-1400 о C on strength, linear thermal movement, electric conductivity, and open porosity is studied. It was fixed, that a “dangerous”, from the point of view of product dehydration and softening, temperature range 600-1000 о С is simultaneously a potentially reaction-favorable one not only for alkaline alumino-silicates formation, but for the replacement of the relaxed and deformed bonds Na-O-Si by stronger ones, for example Mg-O-Si-. Introduction of the corresponding refractory fillers, especially amorphous ones, into alkaline binders promotes the ordering of the structure of alkaline alumino-silicate and alkaline and alkaline-earth silicates, and it enables the formation of a ceramic bond at the expense of more refractory phase crystallization.
Keywords: alkaline binders, soluble silicates and sodium aluminates, properties of refractory binders stone.
Pages: 21-29.
