In mid-July Milan two international conferences were held, SOCAC and RACTSI, on the subject of concrete, dealing in particular with super-plasticisers and chemical additives and innovations regarding cement conglomerate.During the event, some video interviews were carried out with some of the protagonists of the two events.From 10 to 15 July in Milan, at the Sheraton San Siro Hotel, two very important world conferences were held on the topic of super-freezing agents and other chemical additives for concrete, as well as on the most recent innovations in the cement conglomerate sector, referring to also to sustainability issues.The International Conference on Recent Advances in Concrete Technology and Sustainability Issues has reached its 15th edition, while it was the 13th for the International Conference on Superplasticizers and Other Chemical Admixtures in Concrete.Opening the event was Luigi Coppola, conference chairperson, Charles Nmai, ACI International President (WATCH THE INTERVIEW) and Sergio Cavalieri, Rector of the University of Bergamo (WATCH THE INTERVIEW).During the event, the President of the School of Engineering of the University of Bergamo was also interviewed> WATCH THE INTERVIEW.The event was organized by the American Concrete Institute - Italy Chapter and the University of Bergamo - Department of Engineering and Applied Sciences.INGENIO was the media partner of the event.Main topics of the two international events are the following.SOCAC: new superplasticizers for ordinary concrete superplasticisers for concrete based on alternative binders to Portland cement additives for concrete for 3D printing rheology modifiers, retardants and accelerators corrosion inhibitors air additivesase historyRACTSI: artificial aggregates durability of cementitious materials binders alternative to Portland cement ultra high performance fiber reinforced concrete sustainability limestone calcined clay cement restoration of concreteNumerous international Key Lectures were presented during the events.Below we report only some of that presented."40 Years of PCE Superplasticizers - History, Current State-of-the-Art and an Outlook"Johann Plank and Lei Lei, TU Munich, Germany> WATCH THE VIDEO INTERVIEW"Nanoclays as a rheology modifying admixture"Jae Hong Kim, Korea Advanced Institute of Science and Technology, Republic of Korea> WATCH THE VIDEO INTERVIEW“Molecular modeling of chemical admixtures;opportunities and challenges "Aslam Kunhi Mohamed, ETHZ, Switzerland> WATCH THE VIDEO INTERVIEW"Interaction Between Polycarboxylate Superplasticizers and Non-calcined Clays and Calcined Clays"Lei Lei, TU Munich, Germany> WATCH THE VIDEO INTERVIEW"A review of recent advances in the science and technology of seawater-mixed concrete"Federica Lollini, Milan Polytechnic, Italy"Recent advances in the use of inhibitors to prevent chloride-induced corrosion in reinforced concrete"Marco Ormellese, Milan Polytechnic, Italy> WATCH THE VIDEO INTERVIEW"Viscosity modifying agents: key components of advanced cement-based materials with adapted rheology"Marta Palacios, E.
