Gypsum is used to increase the setting time of cement. Rapid hardening cement has more gypsum that is why it is used in underwater construction. So in place of decrease it should be increase.

While doing construction work of dam & in water bodies there is water segregated quickly. So we add less gypsum. Gypsum inversely proportional to setting time.

Why gypsum will sets the cement?

Why gypsum only no other substance has properties like gypsum?

Setting means how quickly it becomes hardened, if gypsum not added then it hardened fast that is not useful in making building so it is added to increase setting time.
I think you understood it.

Because gypsum decrease the time of setting but in case of constructing bridges in across oceans we need to decrease the amount of adding gypsum in cement that will sets quickly.

I think, if the cement sets fastly, it will not be stronger.
