Sergio Lorenzi was born in Calcinate (BG) in 1980. He receives the mechanical engineering degree at the University of Bergamo in 2005 with an experimental thesis on the environmental assisted cracking of carbon steel for marine applications. In 2010 he obtained the doctoral degree in Mechatronics and Innovative Technologies at University of Bergamo with a thesis on corrosion-erosion of steel in fresh concrete. He is research assistant since 2006 at the University of Bergamo in the Material Science and Technology research group (ssd. ING-IND/22) which operates in the field of metal corrosion and durability of concrete structures. The scientific activity is mainly devoted to the study of corrosion of steels and alloys, durability of cementitious materials and concrete reinforcements, microstructural characterization of materials. The main research topics are the corrosion of rebar, the study and characterization of the performances of organic acid-based corrosion inhibitors to be used as chemical admixtures to prevent chloride corrosion in concrete, electrochemical techniques for corrosion protection and prevention of metal structures, the environmental assisted cracking of high strength steels, corrosion in drinking water and energy production plants, cathodic protection design based on numerical simulation. Other research topics are related to concrete technology, the development of innovative admixtures to improve concrete durability, the mix design of high performance cementitious mixtures, green-building and sustainable development in the field of building materials. He co-authored several papers presented at national and international conferences and published in international and national journals. He co-authored an European patent about the composition of a fluid mixture for erosion testing of metals that operates in contact with fresh flowing concrete.
