Ductal is a proprietary pre-mixed ultra-high performance concrete whose physical characteristics exceed those of common concrete used in the construction of buildings. It is manufactured by Lafarge and Bouygues. The concrete has high compressive strength and flexural resistance compared to other concretes. It also has high durability, abrasion resistance, and chemical/environmental resistances (eg. freeze and thaw, salt water, etc.). Due to these properties, the concrete can be used in thinner cross-sections and in more varied applications than common concrete.

Ductal Properties
Compressive Strength	160-230 MPa
Flexural Strength	30-50 MPa
Young's Modulus (E)	55-60 MPa
Density	2.45-2.55 $kg/m^3$
