CEMEX has announced that it has supplied more than 550 000 metric t of aggregates and more than 300 000 m3 of ready-mixed concrete for the Grand Paris Express project, using its network of fixed and mobile plants. To ensure the delivery of optimal quantities of concrete within tight time frames, CEMEX has been able to deploy mobile onsite concrete plants and use its local network of 21 plants in Île-de-France to provide timely delivery and backup.
The future metro station for the Grand Paris Express is a state-of-the-art structure requiring a high level of technical expertise, which must have a guaranteed service life of more than 100 years. High strength of concrete is essential. CEMEX’s formula and quality control staff applied their experience in materials design to provide a highly technical concrete that meets demanding project specifications.
The Grand Paris Express worksites on metro line 11, 14, and several sections of 15 South have involved most of CEMEX’s staff in the Île-de-France region, with four full time operatives working in a dedicated unit. Given the scale of operations, logistical organisation is a major challenge, with the twin demands of delivering construction materials and removing 40 million t of earthwork by 2030.
“The Grand Paris Express worksites present a daily challenge to deliver ready-mixed concrete on time, supply aggregates to our production sites, and move earthworks from the stations and tunnels our of Paris,” said Benjamin Lecendrier, Major Projects Director at CEMEX France. “With our wealth of experience, we can commit significant resources and draw on our full range of expertise to support a sustainable and responsible Grand Paris.”
