Title: Ultra-High Performance Concrete With Ductility: Design, Prototyping And Manufacturing Of Panels And Boxes
Author(s): Don Zakariasen and Vic Perry
Publication: Special Publication
Appears on pages(s): 71-88

Abstract:Ductal® is a new material technology offering a unique combination of superior characteristics including ductility, strength, and durability, while providing highly moldable products with a quality surface. The technology provides compressive strengths up to 200 MPa (30,000 psi), and flexural strengths up to 50 MPa (7,200 psi). The material’s unique combination of superior properties enables the designer to create thinner sections, longer spans, and higher structures that are lighter, more graceful and innovative in geometry and form while providing superior durability and impermeability against corrosion, abrasion, and impact. This material provides the precast industry with opportunities to improve many existing products and manufacture new products that will compete with other materials such as stainless steel, cast iron, ceramics, and others. This paper presents properties of the material, design assumptions for project solutions and the manufacture, installation and assembly procedures for specific projects including roof panels, 5 sided-boxes and anchor plates. Many economies gained from this new technology are a result of engineering new solutions for old problems. By utilizing the unique combination of superior properties, designs can eliminate passive reinforcing steel and experience reduced global construction costs, form works, labour and maintenance. Additionally, this relates to benefits such as improved construction safety, speed of construction, extended usage life and others.
