    Master X-Seed 55 is a patented, strength-enhancing admixture that improves both early and late-age strength development in concrete, while supporting sustainable construction. Master X-Seed 55 admixture is based on a unique technology that facilitates improved cement hydration, thus enhancing strength development. The strength-enhancing property of Master X-Seed 55 admixture permits a reduction in the total cementitious materials content of given concrete mixture while maintaining compressive strength development equivalent to that of reference concrete with associated benefits in CO2 emissions reductions.

    Recommended uses:

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

    What are the features of Master X-Seed 55 strength-enhancing admixture

    • Improves cement hydration
    • Increases strength development – both early – (1-day) and late-age (28-day)
    • Enhances workability of high-performance concrete mixtures

    What are the unique benefits of Master X-Seed 55 strength-enhancing admixture

    • 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 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.​
