Lafarge Holcim Supplies Special Concrete For New Mexico City Airport

feature-top

Lafarge Holcim’s concrete solutions used for the airport were developed by the Group’s Mexican technology centre in collaboration with Lafarge Holcim’s global R&D centre in Lyon, France. They are designed to withstand aggressive sulphate conditions and chloride attacks for 75 years. These special qualities were necessary as the airport is built on the former Texcoco Lake with its high concentration of salts. The concretes developed for this project are unique to the Mexican market. Thanks to their sulphate resistant cement and low alkali aggregate reactivity, they help prevent cracks and other damage to the structural integrity of different airport applications. In July 2017, Lafarge Holcim started delivering material for the passenger terminal construction from an on-site concrete plant that was specifically set-up to secure on time supply. The plant is producing concretes for the first construction phase of the new airport, expected to be completed in 2020.
