Influence of Calcination Level of Recycled Gypsum on the Physical Properties of Hardened Gypsum Slurry
Original language description
This article examines the effect of incomplete calcination of wasted recycled hardened gypsum. Waste gypsum originated from the process of recycling plasterboard. As part of the processing, the cardboard is separated from the hardened gypsum and the gypsum is physical and mechanical activated (calcined) by means of high-speed grinding. As part of recycling, there is no complete calcination of hardened gypsum. In the resulting gypsum composite, these uncalcined grains have a fundamental influence on the process of hydration and its resulting physical properties of hardened gypsum slurry. In the research, the percentage of uncalcined grains was simulated by adding non-activated recycled hardened gypsum to the mixture in the required amount from 0 to 1 wt. %. Compressive strength and flexural tensile strength were measured on hardened gypsum slurries measuring 40 x 40 x 160 mm. The possible processing time of gypsum slurry (setting time) was other monitored parameters.
