Structures

You will find here all the references concerning the different structures made of Ductal®.

The structure of the new cement terminal in Detroit rests on four 17-metre high columns made of Ductal®. The originality of this project is that with a resistance superior to traditional concrete, the Ductal® realisation provides a structure for a 56-metre high silo with columns that are 4 times thinner. This particularity cleared space for lorry loading zones.
The easy implementation of Ductal was another plus because the 13 cubic metres required for each column could be directly transported by two pre-prepared mixer lorries and poured on site in 30 minutes.

The project at Reunion Island involved stabilizing a retaining wall on the water’s edge, the entire length of the coastal road. The original support structure which reinforced the roadway, was built of precast building slabs and badly damaged.
To strengthen the wall, underground anchoring systems were connected to distribution plates made of Ductal®, fastened on the embankment facing the ocean.
In all, 6 300 Ductal® with organic fiber plates and 200 Ductal® with steel fiber plates were installed. The Ductal® solution met all cost and maintenance requirements and other project demands such as production under three months, lightness and ease of installation.
Today, the Ductal® anchor plates secure a strong, durable sea wall that is resistant to marine corrosion and requires very little or no upkeep.

EDF was looking for a building material that was lightweight and highly resistant to the aggressive physical-chemical atmosphere (run-off water, alternating freeze-thaw cycles).
The project included beams and girders for the support building of the heat exchange structure. Ductal® was selected for strength, durability, low maintenance, and its unrivalled mechanical capabilities.
Ductal® reduced the structural weight on the foundations by a factor of three, providing for increased structure lifetime.
In total, more than 2 400 prestressed girders and beams (20 per day), were produced with Ductal®.

Upgrading of the Queen Sofia Museum in Madrid, Spain required construction of three new buildings with a load-bearing structure consisting of 24 steel columns, 16 meters high and 32 cm outside diameter.

These load-bearing columns are reinforced with concrete cast inside the column. This project was the first to cast Ductal® in-place.

Ductal® added compressive and flexural strength, ensuring stability of the load-carrying capacity and the entire column was filled in one pour.

A special fire resistant formula was used to meet the structure design specification.

The Shawnessy LRT Station in, Calgary (Canada) provides an excellent demonstration of Ductal®’s ability to facilitate unique, innovative creations.
Twenty-four white, ultra-thin curved shell-shaped canopies (just 20 mm thick) protect passengers from the elements, and enhanced lighting to the platforms below.
The station, was designed by architect Enzo Vicenzino (CPV Group Architects & Engineers Ltd.). Ductal® was used to build the canopies, struts, columns, beams and rain gutters.
The result – amazing artistic creativity and significantly stronger structural strength, validated by the Center for Innovative Technology at the University of Calgary. The extremely durable canopies are also easy to clean and require very little maintenance.
