    ​Master X-Seed 100

    Set and hardening accelerating admixture for concrete

    Decreasing energy requirements while increasing productivity with no compromise on concrete quality might sound unachievable, but new admixture technology is making these apparently opposing objectives an achievable reality.

    Master X-Seed 100 is optimised for all concretes, and is especially useful in the production of structural precast elements where high early-strength development is a critical success factor. Master X-Seed 100 is a viable alternative to heat curing methods, and its significant impact on hydration supports the use of binders with lower clinker content.

    How does Master X-Seed 100 work?

    Master X-Seed 100 is an engineered suspension of crystal seeds containing nanoparticles, designed to boost the hydration process of early age cement (6-12 hrs). It strongly accelerates the essential growth of calcium silicate hydrate crystals using unique and innovative seeding technology.

    Master X-Seed 100 promotes concrete hardening at low, ambient and even heat-curing temperatures. Unlike traditional acceleration methods, early strength development is boosted by a unique mode of action – the virtually barrier-free crystal growth of the seeds between the cement grains – while the final microstructure benefits from equivalent or improved properties.

    Crystal Speed Hardening

    Master X-Seed 100 is the essential component of Master Builders Solutions' Crystal Speed Hardening concept – the value proposition offered by Master X-Seed's unique crystal seeding technology:
    • ​Efficient​ processes
    • Energy reduction
    • Material optimisation
    • High-quality specifications

    The concept addresses critical industry requirements and can outperform all alternative solutions, particularly in contributing significantly to meeting sustainable construction targets.

    What makes Master X-Seed 100 different? 

    Master X-Seed 100 brings numerous benefits:
    • ​Early strength acceleration at low, ambient and heat c​​uring temperatures
    • Flexible adjustment of production capacities
    • Increased production cycles (double, triple rotation)
    • Better use of formwork by earlier demoulding
    • Reduction/elimination of heat curing
    • Lowers investment and running cost of curing
    • Facilitates minimum required cement quantities
    • Allows binder optimisation: using lower grade, less clinker-containing cements or increasing use of supplementary cementitious materials (limestone, fly ash, slag)
    • Less risk of delayed ettringite formation
    • Reduced water absorption
    • Improved concrete durability
    • Reduced CO2 emissions for improved plant and product eco-efficiency
