Master X-Seed 44

Strength-enhancing admixture

How does Master X-Seed 44 work?

Master X-Seed 44 is a patented, strength-enhancing admixture that improves very-early age (<16 hours) strength development in concrete, without negative effects on 28-day strength development. Master X-Seed 44 admixture is based on a unique technology that facilitates improved cement hydration, thus enhancing very-early age strength development. Master X-Seed 44 admixture meets ASTM C 494/C 494M requirements for Type S, Specific Performance, admixtures.

Recommended uses:

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

What are the unique features of Master X-Seed 44?

Improves cement hydration
Increases very-early age strength development (<16 hours) with no adverse effect on 28-day strength development with a wide spectrum of cement chemistries and binder system combinations
Enhances workability of high-performance concrete mixtures depending on cement chemistry and product dosage

What are the benefits of Master X-Seed 44?

Ability to achieve Type III cement performance with Type I/II cement
Reduces in-place concrete costs when utilized in optimized concrete mixtures
Ability to reduce/eliminate heat curing to achieve early strength development
Permits higher replacement levels of supplementary cementitious materials (SCMs)
Permits reduced cementitious material contents while maintaining early and later age strength development
Permits earlier stripping and reuse of forms
Helps reduce CO₂ emissions associated with concrete

Master X-Seed – The Solution for Reducing the Embodied Carbon of Concrete

Master X-Seed technology is capable of reducing embodied carbon in concrete mixtures by 5 to 20 percent. It is the only stand-alone admixture capable of enhancing concrete strength while lowering cement content. When utilizing Master X-Seed admixture in combination with other Master Builders Solutions admixture technologies, embodied carbon in a concrete mixture can be reduced by as much as 30 to 50%, without sacrificing strength and durability requirements.
