​​​​​​Master X-Seed 66​

Water-Reducing and Strength-Enhancing Admixture​

​Master X-Seed 66^®​​ is a patented​, water-​reducing a​nd strength-enhancing admixture that improves both early- and late-age strength development in concrete, while supporting sustainable construction. Master X-Seed 66 admixture is based on a unique technology that facilitates improved cement hydration, thus enhancing strength development. It includes polycarboxylate technology that helps produce concrete mixtures with different levels of workability. Master X-Seed 66 admixture meets ASTM C494/C494M requirements for Type A, water-reducing, admixtures. 

The strength-enhancing property of Master X-Seed 66 admixture permits a reduction in the total cementitious materials content of a given concrete mixture while maintaining compressive strength development equivalent to that of reference concrete, with associated benefits in CO_2​​ emissions reduction.

Recommended Uses of Master X-Seed 66:

• Green Sense^® concrete
  
• Ready-mixed concrete
• Prestressed concrete
• Precast concrete
• Self-consolidating concrete (SCC)
  

​What Are the Features of Master X-Seed 66 Strength-Enhancing Admixture?

• Improves cement hydration
• Increases strength development — both early- (1-day) and late-age (28-day)
  
• Reduced water content for a given workability​
  

What Are the Unique Benefits of Master X-Seed 66 Strength-Enhancing A​dmixture?

• Improved workability
• Provides a strength safety factor and/or expanded performance space
• Reduces in-place concrete costs when utilized in optimized concrete mixtures
• Permits higher replacement levels of supplementary cementitious materials (SCMs)
• Permits earlier stripping and reuse of forms
• Helps reduce CO​₂ emissions associated with concrete​​​​
