<\/span><\/div><\/div>\n\nThis approach began with alternative solutions proposed at the study phase:<\/p>\n
\n- Optimisation of the beds level of anchors on part of the linear section: reducing the need for cutting\/filling.<\/li>\n
- Optimisation of the return quay: reducing the need for concrete and steel.<\/li>\n<\/ul>\n

The collaboration between the sales teams, the materials laboratory and the works teams made it possible to adopt low-carbon approaches for the concrete used. In fact, the concrete used for phase II of Port 2000, completed from 2007 to 2010, were already very low carbon (163kg CO2<\/sub>\u00a0eq\/m3<\/sup>).<\/p>\nFor phase III, 35,000m3<\/sup>\u00a0of very low-carbon concrete (140kg CO2<\/sub>\u00a0eq\/m3<\/sup>) and 1000m3<\/sup>\u00a0of ultra-low-carbon concrete (97kg CO2<\/sub>\u00a0eq\/m3<\/sup>) are being used. <\/strong>And in order to perfect our knowledge of these materials, we will be constructing a barrette using binder made from activated slag (88kg CO2<\/sub>\u00a0eq\/m3<\/sup>), ultra-low-carbon concrete, a first for Soletanche Bachy France<\/a>!<\/strong><\/p>\nThis trial will enable us to complete our reference catalogue for low-carbon and ultra-low-carbon concrete.<\/p>\n

Lastly, the works teams, meanwhile, have put in place the measures necessary for sustainable management of drilling mud, with the used\u00a0diaphragm wall<\/a>\u00a0mud being returned to the grout production plant, thereby avoiding the elimination of 12,000m3<\/sup>\u00a0of mud and 600 truck rotations.<\/p>\n <\/p>\n

GLOSSARY<\/h4>\n\n- Blast-furnace slag<\/strong>: an artificial mineral produced by the iron and steel industry. Slag is an industrial co-product that can be used to partially replace the clinker present in cement, enabling the production of low-carbon or ultra-low-carbon concrete. Clinker is responsible for cement\u2019s high carbon footprint.<\/li>\n
- Activated slag<\/strong>: a combination of blast-furnace slag and an alkaline activator which allows concrete to harden.<\/li>\n
- Fossil energy<\/strong>: \u201cfossil energy\u201d is the name given to the energy produced by the combustion of coal, oil and natural gas. These fuels, rich in carbon and hydrogen, come from the transformation of organic matter buried in the soil for millions of years (hence the term \u201cfossil\u201d).<\/li>\n
- Clinker<\/strong>: a constituent of cement, which results from the firing of a mixture of limestone and clays.<\/li>\n<\/ul>\n<\/div>\n<\/div>\n\n\n\u00a0<\/div>\n<\/div>\n<\/div>\n<\/div><\/div><\/div><\/div><\/div>\n\n<\/div><\/div><\/div><\/div>\n<\/div><\/div><\/i>Find out more about Soletanche Bachy France<\/span><\/a><\/div>
