Sustainable Construction

Climate changewaste and water management are major challenges for the construction industry. 
Discover how CHRYSO, as a construction chemical company, innovates to bring solutions to this new challenging environment.

Reduction of carbon footprint

Picto CO2
  • Low Co2 cement
    Clinker factor reduction in cement can be achieved thanks to activation technologies.

  • Low Co2 concrete
    • Increase the use of alternate binders both in cement and concrete:
      • SCM (fly ash, slag, filler, calcined clay…), in concrete or in blended cement.
      • Innovative binders. Ex: geopolymers.
    • Fostering the production of low CO2 concrete in partnering with innovative start-up and major players/stakeholders of the construction industry.
  • Energy savings
    • Cement plant: energy savings during the grinding process.
    • In precast: optimizing heating timer during curing process.
    • In concrete: use of local sourcing to decrease logistics fuel consumption.
Our solutions
Designed to limit the environmental footprint of cement production, by enabling the substitution of clinker by more environmentally friendly and cost-effective materials.
Enables extensive use of SCM whether in concrete or in cement, without compromising on materials performance.
CHRYSO®Quad technology
Allows for local aggregates sourcing with a limited CO2 transportation impact.
An innovative service for real-time and remote concrete maturity monitoring, that contributes to reduce energy consumption and thus CO2 emissions.
Our solutions
CHRYSO®QUAD technology
Allows the use of a wider range of aggregates, including challenging sands, facilitates the use of local resources, optimizes procurement costs and lowers CO2 emissions.
Allows for the reuse of returned concrete and concrete plant waste materials.
Improves robustness of pervious concrete.

Circular construction

Circular Economy
  • Eco-design of our products (life-cycle analysis)

  • Use of recycled materials and local aggregates (sands, manufactured aggregates…)

  • New materials produced thanks to returned concrete

  • Waste water treatment and water capture

Densification of construction

Picto densité
  •  Vertical construction (high rise buildings) that requires vertical and/or long distance concrete pumping.

  •  Underground construction & mass transportation infrastructure
    • Concrete with low water-to-cement ratio and high-strength concrete
    • Extended durability of concrete works

  •  Concrete transportation issues imply more slump retention needs.

  •  Precast building
    • Accelerates construction cycle/planning (faster deshuttering time).
    • Modular construction.

CEO Thierry Bernard

For decades, innovation for the construction materials has been dominated by performance (more resistance, less weight, easier to implement, faster, ….) and total cost of ownership.
A new axis is entering into play: sustainable construction including themes like low-carbon construction and the reduction of the environmental impact from the construction to the exploitation of a building.
The combination of these three dimensions brings exciting technical & marketing challenges for a company like ours!
We have multiple technologic platforms to provide solutions to our customers and thanks to our renewed research efforts, we will actively participate on their side to the development of the construction industry who deeply cares about its environmental footprint.
