Abstract: A method of accelerating the setting reaction of calcium sulphate hemihydrafce and water comprises the steps of mixing water and calcium sulphate hemihydrate to produce a slurry adding an accelerator to said mixture applying ultrasonic energy to said mixture. Application of ultrasound to the plaster slurry accelerates crystallization and thus reduces the setting time. A further benefit is reduced density of the wall boards.
