Finalità
The course deals with the applications of the fundamentals of Chemistry in the use of civil engineering materials. It presents a variety of building materials, in particular cements and concretes, metallic and polymeric materials, and correlate their chemicophysical nature with their mechanical, and processing properties for explaining their behaviour in service.
