Behavior of gypsum-based mortars with silica fume at high temperatures

Popis výsledku v původním jazyce

The influence of high temperatures on the ternary and binary gypsum-based mortars is described. The gypsum-based mortar with ternary binder, composed from gypsum, hydrated lime and silica fume and mortar with binary binder, composed from gypsum and hydrated lime only were exposed to the temperatures from 50°C to 1000°C and their physical and mechanical properties were investigated. The comparison of ternary mortars and mortars without silica fume was carried out. The results were also compared with the results obtained from previous testing of gypsum-based pastes without sand. It was found, that gypsum-based mortars have better stability than gypsum-based materials without sand. Ternary materials have better volume stability than materials without pozzolan (about 5 % at 1000 °C).
