OPTIMUM 380 Premium High Range Superplasticizer, Gallon

Modified polycarboxylated high range water reducing admixture formulated to produce self-compacting type (S.C.C.) concrete.  

  • Produces extremely high spread rates
  • High early strengths with improved densification of surfaces
  • Improves workability and greater fluidity with reduced or minimal vibration 
  • Improves dispersing action resulting in concrete with “self placing” properties
  • Very low water to cement ratios can be obtained with as much as 25-30% total water reduction.
  • Greater water reduction and lower dosage rates than comparable S.C.C superplasticizers
  • Improves flow (self leveling) with self-healing rheology
  • Typical dosage rates approximately 40% less than of standard melamine and naphthalene based superplasticizers, while maintaining the same percent water reduction.
  • Available in 1-gallon, 5-gallon & 55-gallon sizes

Recommended Dosage:

  • 3-5 ounces per 100 lbs. of cement (56 –93 ml/100 kg)
  • A good starting point and very easy way to calculate dosage is 1-mL per 1-pound of cementicious material.  So if you have 34pounds of Portland simply add 34mL of OPTIMUM 380.

    Amazing on how well this works. A tiny bit changes the flow a lot.
