MICROSTRUCTURAL ASPECTS OF HIGH TEMPERATURE TREATMENT OF ALKALI ACTIVATED SLAG
Popis výsledku v původním jazyce
The paper covers the result on the study of microstructural changes of alkali activated granulated blast furnace slag exposed to high temperatures. Paste prepared from slag activated with solid sodium silicate glass was subjected to temperatures in the range of 200-1200 deg C for the period of 1 h. The microstructural changes caused by the heat were investigated by means of SEM, HT-XRD analysis and FTIR and MAS NMR spectroscopy. The study revealed depolymerization of CASH binding phases and crystallization of akermanite as a dominant phase at temperatures above 700 deg C.
