    ​​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 Ty​pe 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.​​
