Kitsenko T. Refractory alumina-silicate and silica concretes on the basis of modified alkaline binders

It is theoretically grounded and experimentally confirmed, that the chamotte-kaolin dust and amorphous ultradisperse silica show an active structure-forming role at, respectively, hardening and heating alumina-silicate and slag-alkaline silicate binders on the base of aluminates and low-module sodium silicates; there have been fixed relations between refractoriness and parameters of deformation temperature at a standard pressure 0,196 МPа of alumina-silicate compositions at the content of Al2O3 30-95 % when 2-6 % Na2O being introduced; structural - phase changes occuring in a stone of binding matrixes at hardening and heating up to 1600°С have been investigated; the results of research have been introdusid when manufacturing non- roasting products for lining pouring ladles.
