Water reducers are used in concrete mixtures to lower the water content in the plastic concrete (i.e. uncured concrete) to increase its strength and to obtain higher slump without adding water. Water-reducers will generally reduce the required water content of a concrete mixture for a given slump and are useful for pumping concrete and in hot weather to offset the increased water demand.
