Abstract: A gypsum stucco composition comprising the following components finely divided; calcium sulphate hemihydrate in calcined solid beta crystalline form; and in intimate mixture with said finely divided calcium sulphate hemihydrate and mixed therewith no later than calcination to form the hemihydrate, a sulphate salt comprising at least one of ammonium sulphate and aluminium sulphate, in an amount such that when the stucco composition is mixed with water and allowed to set, the resulting set plaster has increased compressive strength, flexural strength and/or E-modulus compared to a set plaster produced from said finely divided calcium sulphate hemihydrate containing no said sulphate salt.

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.

Abstract translation: 加速硫酸钙半水合物和水的凝固反应的方法包括将水和硫酸钙半水合物混合以产生向所述混合物中加入促进剂的浆料，向所述混合物中施加超声波能量。 将超声波应用于石膏浆加速结晶，从而减少凝固时间。 另一个好处是减少墙板的密度。
