The large structures entrusted to us by our clients are sometimes located in areas subject to extreme climatic conditions (extreme cold, desert, ocean, etc.); we have a good understanding of how the material behaves in these aggressive environments<\/strong>.<\/p>\n

<\/p>\nSpotlight on the new Assiut Barrage<\/strong><\/em><\/p>\n
For example, for the construction of the new Assiut Barrage in Egypt; the local aggregates were alkali-reactive. The cost of finding ‘compatible’ aggregates 200 kilometres from the project site was a major constraint that we were able to overcome. We formulated a concrete with local aggregates and selected a suitable binder (Portland cement, ground slag, limestone filler), keeping the budget within the client\u2019s envelope and significantly reducing the carbon footprint of the project.
\nAs a world-renowned concrete specifier\/formulator<\/strong>, we analyse specifications and design predictive formulas for accurate costing and calibration of production equipment. Each part of the construction has its own formula. No fewer than 40 different concrete formulas were required wiith the creation of the Rion-Antirion bridge.<\/p>\n<\/p>\n
THERMAL BEHAVIOUR OF MODELLED CONCRETE<\/h4>\n
One of the current issues related to the use of concrete is its thermal behaviour during hardening. Thanks to 4 theses that we have produced over the last 10 years in partnership with the Materials and Durability of Construction Laboratory of Toulouse and our involvement with international scholarly associations, we have developed tools for modelling the behaviour of concrete in its early stages of development<\/strong>, which were awarded the VINCI Innovation Award in 2015.
\nOur expertise<\/strong> in thermo-mechanical<\/strong> phenomena also allows us to model and justify the means used to prevent or limit the cracking of concrete at a young age.<\/p>\nA REDUCED ENVIRONMENTAL FOOTPRINT<\/h4>\n
