LafargeHolcim ready-mix concrete onboard a high-speed railway in Lombardy, Italy

In the wake of its initiative to boost high speed train transportation, the Italian government launched the construction of the 40-km long Treviglio-Brescia high-speed railway. For this major rail transport infrastructure, LafargeHolcim provided a comprehensive solution, including ready-mix concrete supply and technical expertise for quality control and mix design.

 

The Treviglio-Brescia high-speed railway was one of the major transportation projects led by the Italian authorities to extend high-speed rail connections on the European corridors, with a EUR 2.1bn budget.

Started in 2010, its objective was to connect cities in the Lombardy region, in the East of Milan, while accommodating train speeds up to 300km/h. Over its 40-km span, the railway required the construction of 7 bridges and 5 tunnels, as well as the adaptation of the central station in the city of Brescia.

LafargeHolcim concrete and expertise at full speed!

To date, LafargeHolcim has supplied 800,000m3 of ready-mix concrete (of which 400,000 directly to general contractor and 400,000 indirectly with suppliers of general contractor), as well as a series of services fitting the project’s technical requirements:

  • Qualification of mix designs for products with strength class higher or equal than 30 MPa including testing of modulus of elasticity, shrinkage, permeability
  • Audit of ready-mix concrete plants (technical characteristics, capacity, loading system, raw materials testing, calibration of scales and water/ additive meters, Factory Production Control)
  • Ready-mix concrete testing at jobsite (workability, water cement ratio and air content)
  • Periodical control of raw materials at production plants
  • Management of strength test specimens (storage, curing, handling, breaking)

We also added specific input, such as cleaning of ready-mix concrete waste at jobsites, or the supply of pozzolanic cement.

The Treviglio Brescia high-speed railway is expected to be commissioned in 2016 and should further help reduce traffic delays between Brescia and Milan.
