A water reducer will increase the psi at later times, however, will retard the set minimally. This typically equates to about a half-hour later set time.
Some water reducers have no effect on set times.
Start with half the normal dosage and adjust according. However, air-entrainment admixtures are compatible when added separately. The total volume of concrete will be reduced proportionately and therefore must be adjusted by this factor. Start with half the normal dosage and adjust according. Compressive strength is increased, less water is required, no plasticizer is required, shrinkage cracking is reduced or eliminated.
