In the design and development issues concretes a characteristic of composites is that the concrete design of the traction performed. In 1998 he made the first high-strength concrete and shrinkage compensated with additives such polycarboxylates in Morlans Viaduct in San Sebastián (fck> 50MPa) and vinyl based additives on the bridge of Spanish in Valladolid (fck> 60 MPa), in 2000, the Arc de los Tilos (fck> 80 MPa) up to now (fck> 150 MPa). The viaduct section Sagar in Eibar - Bergara (N) of the Basque Country highway design a quick-setting concrete and without retraction (fck> 35 MPa) to move quickly on issues centering on the building. p>
The topics mentioned repair and reconstruction repair girders heads in Hendaye (France - 2004) and some viaducts like the stretch Larreategui Eibar-Bergara (N) of the Basque motorway. In the last year has been dedicated Composites ID to obtain concretes with high ductility, compressive strength> 150 MPa and durability> 250 years.
Composites ID is a company dedicated to the execution of special projects wing in the construction sector.
It has a Research and Innovation Center recognized nationally and internationally.
Among its goals is the certification and testing of materials for use in the actual work (innovation)
In 2011, Composites ID has consumed the order of 30 tons of epoxy injections of dams and repair of concrete structures, especially airside airport facilities.
