Decarbonize the cement-concrete sector by manufacturing a low-carbon concrete

To guarantee the durability and strength of concrete over a period of 50 years (conventional buildings) to 100 years (civil engineering structures), it is essential to comply with strict standards and authorized clinker thresholds. In France, standard NF EN 206+A2/CN specifies the requirements applicable to:

• concrete constituents (aggregates, hydraulic binders, water, etc.);

• properties of fresh and hardened concrete (e.g., concrete strength) and their verification;

• limitations imposed on the composition of concrete;

• Concrete specifications: the exposure class corresponds to the environment to which the concrete will be subjected (frost, carbonation, salts, etc.), and the strength class is linked...
