Ductal~reg; : ULTRA HIGH-PERFORMANCE CONCRETE TECHNOLOGY WITH DUCTILITY

摘要

Ductal~®, a new material technology developed over the last decade, is a combination of superior technical characteristics of strength, ductility and durability, whilst providing high quality surface aspect on moldable products. This technology offers flexural resistance exceeding 40 MPa with ductility and compression strength beyond 200 MPa. As a result of its tensile strength and ductility it is possible to avoid reinforcement bars in structural elements. Ductal~® covers a range of formulations that can be adapted to meet specific demands of different customer segments, enhancing the usage value and contributing to the overall construction performance, reducing labor requirement, enhancing durability, lowering maintenance need and increasing total life cycle. Ductal~® 's unique combination of superior properties enables designers to create thinner sections, longer spans and higher structures that are lighter, innovative in geometry and form, while providing superior durability and impermeability against corrosion, abrasion and impact. A number of reference prototypes in Ductal~® already exist in different countries both in structural and architectural segments. A number of selected references as the recent footbridges, retrofitting elements and architectural prototypes will be illustrated in this article. Currently there are many other innovative applications of this material in projects at different stages of development.
