Mechanical performances
The Ductal® product range includes:
- Ductal® -FM
- Ductal® -AF
- Ductal® -FO
Ductal® -FM contains metal 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.
Heat treatment may be applied to Ductal® after setting; subjecting applications to temperatures between 60 et 90°C for 48 to 72 hours. This characteristic enables speed of completion and gives the material dimensional stability immediately after the manufacturing process.
The following table shows the values that are characteristic of the material’s performance. These values are obtained in accordance with experimental procedures outlined in UHPC recommendations.
| Ductal® reveals exceptional behaviour under compression, with resistance 4 to 8 times higher than conventional concretes. Compression behaviour is almost linear up to the maximum stress and shows that there is no damage to the material during this phase. |
| Ductal®-FM contains 2% metal fibers, representing 50 million fibers per cubic meter, giving the material ductility as outlined in the following graph. |
| Ductility occurs when bending is the result of fibers which seam cracks. Multi-cracking can be observed in tensile stressed zones, as the following photo illustrates. |
