Discover Ductal®

Ductal® is a revolutionary ultra-high performance material that possesses a unique combination of superior properties including strength, ductility, durability and enhanced aesthetics. Developed by Lafarge, in collaboration with Bouygues and Rhodia, Ductal® has been designed to serve contemporary architectural creativity and can be used in a highly diverse range of applications.

The result of 10 years of research, Ductal® is an ultra-high performance material with outstanding characteristics that are unique in the world of mineral building materials.

The Ductal® product range includes:

• Ductal® -FM contains metallic fibers and is suitable for structural civil engineering applications such as load-bearing structures.
• Ductal® -AF is a variation of Ductal®-FM that includes the same mechanical properties and, incorporates excellent standardized fire-resistance behavior.
• Ductal® -FO contains organic fibers and is suitable for architectural applications such as wall panels, furniture, canopies, etc.

Ductal® displays superior tensile and compressive strength and unrivalled ductility, which means it can withstand significant deformations without failure, by gradually absorbing the dispersed energy throughout its mass.

Ductal®’s innovative design qualities, which optimally combine a cement-based composite with metallic or organic fibers, result in a range of products with a behavior similar to elasto-plastic materials. Another of Ductal®’s many assets is its outstanding durability, which can significantly reduce maintenance costs. Ductal® is preferred for its resistance to corrosion, abrasion, carbonation and impact strength. It is ideal for structures built in harsh settings such as marine or industrial environments and buildings open to the public, with demanding maintenance and safety requirements.

Ductal® is easy to use ; supplied as a pre-mix that requires no formulation additives or passive steel reinforcement. Ductal® uses conventional concrete equipment and can be cast by pouring, injection or extrusion techniques.

Above all, Ductal® can be used as a self-consolidating material which can replicate fine formwork detail or dry cast, facilitating the creation of highly architectural aesthetic structures.

Ductal® provides the ability to create lighter structures, with reduced volumes and weight, which leads to cost savings on the quantities of materials used, simplifying methods (prefabrication can shorten deadlines) and reducing transportation - all of which facilitate artistic creativity for bridges, tunnels, buildings and other construction sectors.

Due to Ductal®’s properties, it is well suited to civil engineering projects such as foundation reinforcement and pipe production as well as structures like safety vaults and facilities.
