Master X-Seed 100

Hardening accelerating admixture for concrete - EN 934-2: T7

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). Based on unique and
innovative seeding technology, the growth of the
essential Calcium Silicate Hydrate crystals is
strongly accelerated.

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

What is Master X-Seed 100 used for?

Master X-Seed 100 is optimized for all kinds of
concretes, especially for structural precast
elements where high early strength development
is a key success factor for the producer.

Master X-Seed 100 is a relevant alternative to
heat curing methods and the strong promotion of
hydration in particular supports the use of binders
with lower clinker content.

What are the benefits of Master X-Seed 100?

Master X-Seed 100 offers the following benefits:
  • Early strength acceleration at low, ambient
  • and heat curing temperatures
  • Flexible adjustment of production capacities
  • Increased production cycles (double, triple
  • rotation)
  • Better use of formwork by earlier demoulding
  • Reduction / elimination of heat curing
  • Reduced investment and running cost of
  • curing
  • Allows use of minimum required cement
  • quantities
  • Allows binder optimization by using lower
  • grade, less clinker-containing cements or by
  • increasing use of supplementary cementitious
  • materials (Limestone, Fly Ash, Slag)
  • Lower risk of delayed ettringite formation
  • Reduced water absorption
  • Improved concrete durability aspects
  • Improved plant and product ECO-efficiency by
  • reducing CO2 emissions
