Originální abstrakt

The granulated blast furnace slag was activated with dried sodium silicate; the temperature-resistant electrical porcelain as an aggregate was used. Composite has been loaded at the temperature from 200 to 1200 dg. Cels. 28 days after the specimens had been prepared. The treatment to the temperature between 200 and 600 dg. Cels. caused the fallback of the strength to 80 % of the primary one. Further temperature elevation led to compression strength increase that was twice as high as the original strength. The properties of composites after temperature loading were investigated by mercury porosimetry, X-ray diffraction analysis and electron scanning microscopy. The mineralogical composition, microstructure, porosity, and comparison with specimens containing quartz aggregates are described.
