Structural changes of ternary gypsum-based composites caused by drying methods

Popis výsledku v původním jazyce

Effects of different drying methods on structural changes of ternary gypsum-based composites were investigated by mercury intrusion porosimetry. The composites were prepared from gypsum, lime, ceramic waste, and sand. The samples were stored for 28 days in a climate chamber (relative humidity 80%, 20 ± 2 °C), and then, they were crushed into pieces smaller than 5 mm, and these pieces were dried at temperatures of 50 °C and 105 °C. The results obtained by mercury intrusion porosimetry confirmed that even a relatively low drying temperature of 50 °C, which is commonly used for drying cement composites, affects the structure of the gypsum-based composites. It was also found that a composition of ternary mixture with an optimized amount of fine ceramic powder can suppress the negative effect of drying.
