Gypsum not decreases the setting time but it increases (lengthen, retard or slowdown setting time) suppose cement setting time is 30 min, when we can add gypsum to the cement at the time of grinding of clinkers then gypsum can slowdown the setting, setting increases from 30 min to 60 min it means it cannot decreases the setting time decrease means cement setting is 30 min decrease means 30 min to 20 min but this is wrong. Right answer is gypsum increases, lengthen, slowdown setting time of cement.
