Massive carbon reduction in concrete to make it a material of the future

With EXEGY® solutions, VINCI Construction minimises the carbon footprint of your structures.

Context

Reducing the carbon footprint of concrete

Decarbonising the construction sector requires the rollout of low-carbon concrete formulations that replace all or part of the traditional, highly emissive cement.

5%

  • Globally, concrete production is responsible for 5% of greenhouse gas emissions.

Solutions

Our low carbon solutions

Discover the technical standards defining low carbon, very low carbon, and ultra low carbon concrete according to their strength class and the carbon footprint of concretes in kg CO2 equivalent/m3.

Our formulations can reduce up to 70% of CO2 emissions compared to traditional concretes.

  • Compressive strength class of concrete according to standard EN 206/CN

How is low-carbon concrete made?

Substituting clinker

Cement is the component responsible for 85% of CO2 emissions from concrete. The cause is clinker: the main component of cement. Substituting all or part of the clinker results in low-carbon concrete.

  • Reducing CO2 emissions from cement

  • Substituting clinker in concrete formulations greatly reduces CO2 emissions from cement. Our EXEGY® solutions provide low, very low and ultra-low carbon concrete.
Promoting the circular economy and minerals

4/4

  • Promoting the circular economy and minerals.

  • EXEGY® benefits from VINCI Construction’s know-how in substituting cement with materials from the circular economy (blast furnace slag, fly ash, silica fume). The limited availability of these materials has led EXEGY®’s experts to innovate by developing alternative formulations of low-carbon concrete in which cement is partly substituted by other mineral additions (limestone filler, pozzolan, metakaolins).

EXEGY®’s construction solutions are suitable for all uses in the construction sector and are implemented on all types of structures, both buildings and infrastructure.
