The contract concerned the supply of various types of cement conglomerate for the construction of a new commercial building in Desenzano d / G (BS) (2015-2016).
The client's goal was to certify the 'New Office Building' project according to the LEED protocol, with GOLD certification level.
To do this, it has taken advantage of several solutions including the supply of concrete containing recycled material (artificial aggregate and from recovery). Concrete
was then supplied with the highest possible percentage of post-consumer and post-industrial recycled content compatible with the technical construction
The company Vezzola has implemented mix designs containing light ash (fly ash) from coal-fired power plants, steel mills from the treatment of black steel scrap and
aggregate recycled from the treatment of selective discarding of only concrete.
Concrete containing recycled material
Evidence of success
Concrete was then supplied with the highest possible percentage of post-consumer and post-industrial recycled content compatible with the technical construction characteristics.
In the first mix the company Vezzola used 36% of recycled materials and in the second the percentage was 18%.
Potential for learning or transfer
In this work the company Vezzola learnt to increase its concrete's production also with the introducing of a high percentage of recycled materials.
The company bought a new system to remove steel bars and smash the materials whose use has allowed an increase of recycled materials.
The system is made by a sandvik powertrack, a machine which can also works with demolitions and asphalt.
