In the precast industry, concretes made with the CCB limestones stand out with the following characteristics :
- Increased resistance
- Calcium reserve improving resistance to acids
- Low expansion coefficient and better resistance to fire
- Low thermal conductivity – insulation and fire resistant
- Crushing index (100%) and shape of the aggregate enable an excellent set-up with optimal demoulding
