CHRYSO®ICARE technology

A New way to Process Cement Reactivity

CHRYSO®ICARE is a new patent-pending innovation that boosts cement compressive strengths to significantly reduce clinker factor and therefore cement CO2 footprint.
CHRYSO®ICARE is a disruptive technology developed into 2 ranges:

  • CHRYSO®ICARE CP for challenging grinding processes
  • CHRYSO®ICARE VRM and Vertical Roller Mills

Innovative cement additives for CO2 reduction

CHRYSO®ICARE patent-pending technology has been developed to support the Cement industry in lowering cement carbon footprint.
CHRYSO®ICARE strength enhancers enable to achieve unequalled performance:

  • Cement extra activation at all ages
  • Improved cement transport properties
  • Energy & production cost savings
  • Reduction of the clinker-to-cement ratio and CO2 emissions


Especially designed for Vertical Roller Mills, CHRYSO®ICARE VRM additive range allows to achieve higher cement compressive strengths by overtaking process limitations:

  • Optimization of mill stability by reducing ΔP and vibrations in the process.
  • Improvement of cement reactivity by reducing water injection.
  • Overall increase of cement compressive strengths at all ages to significantly reduce clinker factor.

CHRYSO®ICARE CP additives provide full cement activation potential by better controlling cement transport properties in ball mill or Horomill®-based processes:

  • Improvement of your cement fineness and particle size distribution by increasing the process efficiency.
  • High increase of productivity by keeping control on cement fluidity.
  • Reduction of your production and energy costs at equal or better cement overall performance.

Improving VRM stability to achieve higher clinker factor reduction

In some specific process conditions (e.g. Vertical Roller Mills), the use of conventional high performance strength enhancers can lead to process limitations. These sides effects are often controledcontrolled by reducing the dosing rate of cement additive. However, this leads to a lack of grinding aid in cement to achieve all the benefits from the chemicals. […]

Overtaking cement grinding process limitations to reach full cement activation potential

The performance of conventional strength enhancers can be limited by different grinding process constraints. An example is given with a process design based on a combined high-pressure-roller-press with single chamber ball mill and 3rd generation separator. It is stressed a high process sensitivity with strength enhancers. This demonstrates the direct impact of too powerful strength […]

Activation of blended cement by amine additives

In order to reduce CO2 emissions coming from cement production, manufacturers are increasingly making use of supplementary cementitious materials (SCMs). However, the use of SCMs such as slag, fly ash or limestone usually leads to a decrease of cement strength performances, especially at early age. The addition of an efficient activator can allow to compensate this loss of performances. Different molecules and salts can be used […]
