Fishstone Concrete Countertop Supply has released Optimum 380 Premium Superplasticizer. Optimum 380 is a modified polycarboxylate high-range water-reducing admixture formulated to deliver extremely high spread rates and “self-placing” properties.
Using Optimum 380 delivers higher early strength, improved workability and surface densification with lower dosage rates compared to standard superplasticizers for selfconsolidating concrete. Water-to-cement ratios can be reduced by as much as 25 to 30 percent using Optimum 380.
Optimum 380 is available in 1-quart, 1-gallon, 5-gallon and 55-gallon sizes. Its dosage rating is 3 to 5 ounces per 100 pounds of cement material.
