e been studied it 20℃, 25℃ and 30℃ by isothermal method. 1％ CaSO_4·H_2O can increase the hydration rate of anhydrite Ⅱ.In 10％ Nacl aqueous solutions , at 20℃, 1％ CaSO_4·2H_2O accelerates the hydration rate most, K_2SO_4 which concentration is 0.2％ 0.5％ can hardly increase the hydration rate for the concentration of K_2SO_4 is too tittle. 收起
