Master X-Seed 100

Master X-Seed 100 is an engineered suspension of crystal seeds containing nanoparticles, designed to boost the hy- dration 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 tradi- tional acceleration methods and thanks to the unique mode of action
— the virtually barrier-free crystal groMh of the seeds in between the cement grains
— early strength development is accelerated while the final microstructure benefits from equivalent or improved properties.

Master X-Seed 100 is the essential component of BASF’s Crystal Speed Hardening concept. Crystal
Speed Harden- ing expresses the Value Proposition offered by the unique crystal seeding technology
of Master X-Seed 100:

• Efficient Processes
• Energy Reduction
• Material Optimization
• High Quality Specs

The concept addresses key industry requirements and has the power to exceed all current solutions. In particular, the concept is designed to make a significant contribution to meeting sustainable construction targets.

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 pro- ducer. 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.

• 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.
