Cemex supplied reinforced concrete for the Puente La Unidad bridge in Mexico which it says will enable it to have a useful life of around 50 years.
Cemex supplied 34,000 cubic metres of concrete for the project built on the Gulf of Mexico. Spanning a length of 3.2 km, it is considered the second longest bridge in Mexico and the fifth longest in Latin America, providing the new connection between the Mexican state of Campeche and the Yucatan Peninsula.
The infrastructure project is expected to be used by around 5,000 vehicles per day, benefiting the region's tourism, industrial and commercial sectors. The bridge is built to withstand the heavy vehicle loads and the extreme weather conditions of the coastal area, Cemex adds.
Cemex Duramax concrete was chosen for its durability while the company's high-strength Fortis concrete was used to improve resistance. Also, Cemex Ingenia was utilised to improve the concrete's workability.
Alejandro Varés, vice president of infrastructure and government of Cemex Mexico, says: “We also suggested the use of our Promptis accelerated-strength concrete for more efficient time management and stripping and our evolution self-compacting concrete to improve the finish of the beams and facilitate the placement of piles and footings, as well as the installation of a concrete plant dedicated to the project.”
