Optimum Dosage Water For Cement Mill

High-Performance Mix Design - Concrete Decor

Water: 26.1 pounds. Superplasticizer:3 ounces; Optimum 380 should be added at 3 ounces per hundredweight of cement. We have about 1 hundredweight (100 pounds) of cement in our example mix so we'll start with 3 ounces. Add more as needed to maintain your water-to-cement ratio while achieving your desired of fluidity.

Chemical Admixtures - Portland Cement Association

Water-reducing admixtures usually reduce the required water content for a concrete mixture by about 5 to 10 percent. Consequently, concrete containing a water-reducing admixture needs less water to reach a required slump than untreated concrete. The treated concrete can have a lower water-cement ratio.
