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. Ductal has 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. The constituents of Ductal are cement, fine sand, silica fume and silica flour as a filler, additive and water, using a low water cement ratio and may include high-strength steel fibres or non-metallic fibres.
