Choose an incorrect statement regarding water reducers.

Adding a water reducer without altering the other quantities in the mix increases the slump $($workability$),$

Water reducers can directly change the rate of hydration of PCC mixes.

The strength of the mix can be increased by using the water reducer by lowering the quantity of water and keeping the cement content constant.

Water reducers increase the mobility of the cement particles in the plastic mix, allowing workability to be achieved at lower water contents.
