Preparation and Application of the Vesicant in Gypsum

Abstract:

Gypsum and vesicant were used to manufacture foamed gypsum by physical foaming. The effect of different components of vesicant on the properties of bubbles and gypsum slurry were confirmed in the experiments. The changes of dry bulk density and thermal conductivity of foamed gypsum were studied in the conditions of adding bubbles. The results showed that the comprehensive performance was better when adding150ml bubble to 300g gypsum, compared with blank sample, the dry bulk density and thermal conductivity of the samples decreased by 38%, 36% respectively, the dry bulk density was 812 Kg/m³and the thermal conductivity was 0.18 W/m•K.
