CHEMISTRY AND TECHNOLOGY OF ADDITIVES FOR CONSTRUCTION

The teaching is included among the training activities that characterize the three-year degree course in Chemistry and Sustainable Technologies. The course aims to provide students with the basic knowledge necessary to facilitate their integration into the world of work but also to the research in the field of additives for building materials. Some fundamental aspects of work safety and sustainability of industrial production linked to this economic sector will also be proposed and discussed.
This requires a multidisciplinary knowledge ranging from chemistry, physics, to the science of materials, in order to fully understand the most important aspects of the use of chemicals to formulate the commercial products.

1. Knowledge and understanding
Knowledge of the main production of building binders. Knowledge of problems related to the degradation of cements and concretes and understanding of the properties of the main additives used in commercial formulations. Understanding of the environmental impact and critical points of the products taken into consideration.

2. Ability to apply knowledge and understanding
Knowing how to solve practical problems regarding the choice of the most useful cement formulation. Knowing how to create and organize a collection of experimental data related to the rheological properties of cement pastes containing additives. Choose the most suitable products both for new constructions and for restoration.

3. Ability to judge
Know how to evaluate and recognize the cement formulation used in the realization of a specific product. Knowing how to recognize errors through a critical analysis of the "mix designer" activity in a construction site.

4. Communication skills
Knowing how to communicate the knowledge learned and the result of their application using appropriate terminology, both oral and written. Knowing how to interact with the teacher and with the classmates, also with a view to joining a team.
.
5. Learning skills
Knowing how to take notes, selecting and collecting information according to their importance and priority. Being able to be sufficiently autonomous in the application and in the critical evaluation of the themes proposed in the theoretical part.

To have achieved the educational objectives of the General Chemistry course. It is necessary for the student to know the general chemical and physical principles that regulate the behavior of matter.

Lesson notes.

The expected method of assessment of learning consists of an oral test in which it will be verified that the student has acquired the concepts presented during the lessons and knows how to apply them consistently and consistently in order to solve problems.
Through a series of questions that simulate real problems, the student will have to demonstrate both the learning of the topics taught in class and the ability to expose them in a formal way.
The oral exam lasts about 30 minutes and must be sustained on the dates of appeal agreed with the teacher during the exam session.

Teaching is organized in frontal lessons.
In the "moodle" platform of the University there is teaching material (material projected in the classroom).
