OPTIMUM 380 Premium Superplasticizer

OPTIMUM 380™ Premium High Range Superplasticizer

OPTIMUM 380™ is a premium modified polycarboxylate-based high range water reducer engineered for high-performance concrete, GFRC, UHPC, ECC, and self-consolidating concrete (SCC) applications. Designed to dramatically improve flowability, workability, and surface quality, OPTIMUM 380 helps produce highly fluid, self-leveling concrete mixes with reduced water demand and exceptional strength development.

Unlike traditional melamine or naphthalene-based superplasticizers, OPTIMUM 380 delivers superior water reduction at significantly lower dosage rates while maintaining excellent rheology and mix stability. The advanced dispersing action allows concrete to flow more easily into molds and forms, reducing or even eliminating the need for vibration while improving overall consolidation and surface density.

Key Benefits

• Produces extremely high flow and spread rates
• Ideal for self-consolidating concrete (SCC) and highly flowable mixes
• Reduces water demand by up to 25–30%
• Improves workability and self-leveling characteristics
• Enhances surface densification and finish quality
• Helps achieve high early strengths
• Improves particle dispersion for more uniform mixes
• Reduces or minimizes vibration requirements
• Lower dosage rates compared to traditional superplasticizers
• Excellent for GFRC, UHPC, precast, countertops, architectural concrete, and castings

OPTIMUM 380 is especially effective in applications where smooth surface finishes, high detail reproduction, and superior flow characteristics are critical. The advanced rheology also helps mixes maintain workability while reducing segregation and improving placement consistency.

Available Sizes

• 1 Gallon
• 5 Gallon
• 55 Gallon Drum

Recommended Dosage

Typical dosage rates range from:

• 3–5 ounces per 100 lbs. of cementitious material
• (56–93 mL per 100 kg)

A simple starting point for most mixes is:

• 1 mL of OPTIMUM 380 per 1 lb. of cementitious material

Example:
If your mix contains 34 lbs. of cementitious material, begin with approximately 34 mL of OPTIMUM 380 and adjust as needed based on desired flow and performance.
