The Le Havre port worksite \u2013 fertile ground for technical feats! The first trail barrette using EXEGY foundation ultra-low carbon concrete, based on alkali activated slag was poured by Le Havre phase III of the Port 2000 worksite and materials teams.<\/strong><\/p>\n<\/div> On 9 March 2021, teams from the Port of Le Havre built ultra-low carbon concrete barrette at a depth of 17m, using a binder exclusively composed of blast furnace slag activated with sodium carbonate (concrete with a reduced carbon footprint of 71kg CO2<\/sub>\u00a0eq\/m3<\/sup>).<\/strong> The mix design, produced specifically for this worksite, is the result of collaboration between the VINCI Construction<\/a> laboratory and the Soletanche Bachy materials department, in partnership with Ecocem. As well as a local partner, B\u00e9ton Solutions Mobiles, which is open to this type of approach, and a loyal, confident customer, which gave us the opportunity to validate that our quality and robustness requirements for concrete foundations could be fully met under real-life conditions using cements with a very high slag content<\/p>\n And their confidence was rewarded!<\/p>\n This is not the first time that the Grand Port Maritime du Havre has entrusted Soletanche Bachy teams with reducing its structures\u2019 carbon footprint.<\/strong> Other tests have been carried out in the past, but this remains a first for the Group, as well as a first for the VINCI group and the construction industry.<\/p>\n<\/div>
