Learning outcomes of the course unit

Chemical processes of the solid structure of inorganic binder formation, effect on reaction kinetics.
Metals and their chemical and electrochemical properties.
Chemical and biological degradation processes of cement composites, gypsum, lime binders, metals, plastics.
Modelling of degradation processes of concrete.
Water in building materials, composition, chemical and physical properties.

Student gets the aim of subject under control, i. e. chemical processes of the solid structure of inorganic binder forming, chemical properties of metals, plastics, and degradation processes of building materials, include modelling. Student learns the chemical and physical properties of water, the water transport, and negative effect on building materials. Student gets the basic overview on the properties of construction materials.

Prerequisites

Base of general chemistry, kinds of chemical bonds in compounds, reaction kinetics, dissociation, electrolytes, base knowledge of electrochemistry, standard electrode potentials, base knowledge of inorganic chemistry, base of organic chemistry, principal of chemical terminology, stoichiometric calculations.

Co-requisites

The course is studied in connection with the courses of concrete and metal constructions; student gets a more comprehensive view on the life cycle of building structures.

Recommended optional programme components

Students get the offer to take part in the workshops and seminar meetings on chemistry of building materials.

Recommended or required reading

Not applicable.

Planned learning activities and teaching methods

Teaching methods depend on the type of course unit as specified in the article 7 of BUT Rules for Studies and Examinations. The basic teaching methods are lectures and laboratory sessions. In lectures, the students look into relationship between chemical and mechanical processes during the steady state forming. In the laboratory sessions, part of the session is usually aimed at calculations, part at experimental verification of teoretical knowledge.

Assesment methods and criteria linked to learning outcomes

Student elaborates the protocols about laboratory tasks including the results of measurements. The oral exam is endpoint of the course. Student has to demonstrate the solving of the problems of civil engineering work experience.
