Ductal® is a proprietary pre-mixed ultra-high performance concrete whose physical characteristics allegedly exceed those of common concrete used in the construction of buildings. It is manufactured by Lafarge and Bouygues. Ductal® is claimed to have high compressive strength and flexural resistance compared to other concretes. It also has high durability, abrasion resistance, and chemical/environmental resistances (e.g. freeze and thaw, salt water, etc.). Due to these properties, Ductal® can be used in thinner cross-sections and in more varied applications than common concrete. Ductal® is almost self placing and is best suited for precast elements or in-situ repair or upgrade works.
Ductal® is a ductile material that allegedly possesses ultra high compressive strength, high tensile strength and high durability together with high fatigue performance. It also claims excellent impact, blast and abrasion resistance.
typically 160-230 MPa... compressive strength in excess of 750 MPa recorded (see: Cyclic loading and Fracture Mechanics of Ductal® concrete, Ehab Shaheen and Nigel G. Shrive, Springer Science+Business Media B.V.2008, Published online: 8 April2008)
