CEMENT ADDITIVES

Next-generation activators

Next Generation Activators are innovative solutions which can be customized to meet the individual needs of cement producers, providing clinker and CO₂ emissions reduction over and beyond that achieved by traditional activators.

We bring together advanced chemistry, technical expertise, and innovative technologies to help our customers achieve greater strength, sustainability, and cost savings.

• Higher cement performance
  Achieve higher compressive strengths at all ages.
  Leverage clinker factor reduction with no compromise on cement final performance.
• Additional clinker reduction, use of alternative fuels and novel Supplementary Cementitious Materials (SCM)
  Increase the content of Supplementary Cementitious Material in cement to achieve higher energy and production costs reduction.
  Extend the use of locally available mineral additions.
• Improved cement carbon footprint
  Leverage clinker factor reduction to achieve substantial energy savings and CO₂ emission reduction.

Performance activators

Robust chemical additives to achieve improved quality, strength & performance in blended cements, while reducing clinker content.

Cement grinding aids

Our grinding aids are designed to increase mill output without increasing costs, while saving energy and reducing CO₂ emissions.

Improved cement flowability reduces the effort for handling and transporting cement.

• Process optimisation
  Increase mill output at same cement composition and fineness.
  Reduce energy consumption and distribution costs.
• Improved cement quality
  

  Improve cement fineness, thus cement reactivity.
  Leverage cement powder transport properties by improving cement flowability, thus reducing Pack Set Index (PSI).

Chromium VI reduction

Chromium VI (Cr (VI)) in cement is a sensitising agent that can cause allergies and skin irritations in people who handle cement, mortar and concrete. To prevent this, Directive 2003/53/EC imposes a limit of 2 ppm Cr (VI) on European cement manufacturers in their cements.

The presence of Cr (VI) in cement is mainly due to the oxidation of the chromium present in certain materials used in its manufacture. The solution to the problem lies in the addition of an external chemical agent to the cement that can reduce the Cr (VI) – soluble – to Cr (III) – insoluble – which is then no longer absorbed by the skin.

• Durable Chromium VI content reduction
  CHRYSO^®Reductis reduce significantly the Hexavalent Chromium content in cement even at low dosages.
  It allows to maintain durably the Chromium VI content below 2 ppm to be in line with the 2003/53/CE European standards.
• Health of your team
  CHRYSO^®Reductis 6Ø is a no hazard symbols solution.
  It also guarantees the protection of the health of your team and the environment.
• Limited installation and maintenance costs
  
  CHRYSO^®Reductis is a liquid solution easy to introduce through a standard dosing equipment.
  It also limits maintenance costs.

Cement grinding aids for minerals

Our grinding aids for mineral is a range dedicated to calcium carbonate applications from limestone for cement to high-quality calcium carbonate.

More and more cement producers reduce clinker factor in order to save cost and cement carbon footprint. To go further in the clinker content reduction, the finesse and the particule size distribution (PSD) are keystones. Separated grinding is a way to step up the limestone content in cement. Our range enable to master PSD and increases limestone finenesse.

• Clinker factor reduction
  Increased fineness for same energy input.
  Improve calcium carbonate Particule Size Distribution and fineness.
• Reduced grinding cost

ADDITIVES FOR CEMENT MASONRY

Our functional additives let manufacturers improve the quality of their cement while complying with standards such as EN and ASTM. These products impart specific functionalities to cement, such as promotion of air entrainment, and increased workability to the desired level.
