Abstract

The ASTM C 454‒83 method was used to investigate the alkaline resistivity of various refractories (fireclay bricks, conventional and middle cement chamotte castables) the most frequently used in the fire-wood power generating boilers. The alkaline stability of the middle cement castable, developed by the authors, with the aggregate which had been produced out of the Gorcal-50 clinker (manufactured by «Gorka» Works, Poland) was investigated as well. It was defined that the ground quartz glass addition increased significantly the investigated castable's stability against the alkaline salt (K2CO3 was used) at 1100 °C. It was shown that under the alkaline influence this addition facilitates the
protecting layer creating which resists the penetrating of the K2CO3's decomposition products into the material's structure. Ill. 2. Ref. 12. Tab. 3.
