CHRYSO works alongside with its customers, universities and start-up to design the next generation technologies and services
CHRYSO has set up Academic Partnerships and supports many PhD thesis projects.
We also partner with world class laboratories, thus nurturing our knowledge of Cement and Concrete materials.
These unique collaborations pioneer the future of building materials


CHRYSO’s mission is to work closely along with its partners and contribute to the global effort to reduce CO2 emissions.
As an active member of INNOVANDI, the Global Cement and Concrete Research Network, we participate to the accelaration of Innovation on Sustainability.

How CHRYSO innovations respond to the construction challenges?

CHRYSO Optima1000

Increasingly complex jobsites

  • Increasingly complex jobsites require superior tailor-made admixture technologies.
  • The highly adjustable CHRYSO®Optima 1000 concrete admixture technology answers the requirements of major construction projects designed to transcend three specific performances:
  1. Workability retention
  2. Water reduction
  3. Pumpability
Chryso Quad

concrete raw material performance

  • Addressing coarse aggregate and sand issues in the concrete mix is a key lever for concrete producers.
  • Because sands can significantly impact concrete placing and performance, CHRYSO®Quad innovation is based on a unique approach to analyse your sand, considering: excess of fines| clay contamination| lack of fines| shape factor, to provide you with the best-fit admixture solution.
  • CHRYSO®Quad allows the use of a wider range of sands and to achieve cost reductions in sand procurements.

between clay & admixtures


  • Jobsites will be data driven in the near future.
  • CHRYSO, as concrete expert, in partnership with Sensohive digital start-up, have developed a new standard in concrete performance monitoring and prediction.
  • Maturix unique service comprises a cloud-based solution using IoT network and wearable sensors, helping the construction industry to monitor concrete curing and hardening through hydration temperature measurements.
  • Advanced analytics will allow for increased productivity, enhanced concrete quality and mix design optimization.
Green cement

Cement carbon footprint reduction

  • CHRYSO is committed to accompany the ambition of cement manufacturers to reduce their CO2 emissions.
  • Developing breakthrough cement activation technologies providing extra-performance to reduce clinker factor is one of our main goals.
  • Both CHRYSO®AMA 100 EL technology and CHRYSO®ICARE innovation are designed to limit the environmental footprint of cement production in a profitable way, by enabling the substitution of clinker by more environmentally-friendly and cost effective materials.

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 […]

Thixotropy and Fill-Free® admixtures

Cement pastes are thixotropic; left at rest, their rheological constants —among which viscosity— increase over time. Under steady shear, cement paste viscosity decreases (which qualifies it as shear-thinning) but may take some time to reach a steady value (which qualifies it as thixotropic). Flow steadiness is highly useful in most concrete operations; as will be […]

Interaction between clays and polycarboxylate superplasticizers

The robustness of PolyCarboxylate Ether (PCE) superplasticizer performance is challenged by the variable amount of clay minerals in aggregates. It will be shown here how a swelling clay like Montmorillonite interacts with polymers, interfering with their ability to disperse cement particles thus influencing the rheological behavior of concrete. Here, the mechanisms governing this interaction will […]
