Kvalita žárobetonu v závislosti na použitém cementu a výrobních podmínkách

Abstract

This thesis deals with the problem of alkali-resistant refractory castable. Refractory castable is an unshaped mixture contains refractory aggregate and binder. The theoretical part of thesis describes the alkali-castable division, refractory castable mixture composition and the refractory materials properties and usage. The experimental part of thesis deals with the study of the influence of different types of cement and also the influence of working environment on material properties. The mechanical (compressive strength, bending strength) and the physical (bulk density, porosity, water absorption) properties been detected. These properties been compared with commercially available products of the same base.
