Buzzi Unicem received an important accolade during the Concrete Days organised this year in Neu-Ulm in conjunction with the BFT International trade journal. The accolade was for the production technologies category for the development of Nanodur E80 concrete as a ‘latest generation product, characterised by a significantly high modulus of elasticity.’
Normal recipes of high performance concrete reach a young´s modulus between 35,000 to 45,000 MPa, while with the new recipe Nanodur E80 it is possible to exceed the 80,000 MPa. In comparison with a structural component of equal dimensions, the stiffness (in the range of aluminum!) is increased by 100% and the deformations reduce correspondingly. Interesting fields of application may be highly loaded precast elements. The secret of this innovation is the replacement of natural aggregate with the industrially enhanced aggregate durigid. The binder Nanodur Compound 5941 based on Nanodur cement for easy production of UHPC had already won the innovation price in 2008.
