CEMEX supplies 7,500 m³ of concrete for railroad track at France’s iconic Puy-de-Dome

Date published: December 7, 2011

CEMEX is supplying nearly 7,500 m³ of ready-mix concrete for the construction of a railroad track that will transport visitors to the highest mountain in the Auvergne (4,806 ft) in central France. More than a tourist facility, the finished project will be a genuine piece of infrastructure capable of accommodating the 400,000 visitors each year that make their way to the summit of Puy-de-Dôme, the second most visited natural site in France after Mont Saint-Michel.

The complexities of this project require CEMEX’s expertise and specialty products. At the top of the Puy-de-Dome, winds can reach speeds of up to 125 mph and lightning is a constant occurrence. With this in mind, CEMEX chose to pour using a mobile crane, which can be retracted quickly, rather than a more exposed tower crane.

This demanding project is making use of several different types of CEMEX’s specialty ready-mix concretes. At the lower station, CXB® C25/30 concrete is being used for the platforms and the floor slabs of a building that combines a wooden framework, glazed gables and volvic lava stone cladding in local dark colors. The top station, buried for ecological reasons, is created out of pre-cast concrete walls covered in an extra thick raised concrete slab. The approaches to the summit station are to be made of decorative concrete, while underneath, dry cast concrete is being used to conceal the containing walls.

CEMEX’s products are the foundation for construction projects of every type. From wineries to wind farms, the company tailors its products and services to suit its customers’ specific construction needs.
