Learning outcomes of the course unit

In this course students are very closely apprised with the problems of durability of building materials. Attention is focused on the principles of degradation processes caused by different types of corrosive environments (liquid, gas and solid phase), the possibility of protection structures, etc. Students will be able to for example:
♦ Describe in detail the degradation of principles for different types of building materials (concrete, plaster, reinforcement, plastic, etc.).
♦ Analyze the risks to which the structure is exposed to the specific conditions of exploitation.
♦ Describe by the detail way methodological approaches to sleep for durabilitytesting of building materials and apply them in practice.
♦ Optimize the material composition of the structure for the specific conditions of exploitation.
♦ Draw up and apply methods of protection structures in different conditions.
♦ Describe the diagnostic methods used in assessing the condition of structures.
♦ Assess by objective way the state respectively the degree of degradation of the material.

Prerequisites

♦ The knowledge of general and physical chemistry. The basic knowledge in branch of physics in building engineering. The basic knowledge in silicate chemistry.

Co-requisites

♦ General knowledge of physical chemistry. Knowledge in the field of physics applied in the construction industry. Fundamentals of Chemistry in the structure of silicates. Orientation in the methods used in evaluating the state of materials (XRD analysis, gravimetric analysis, etc.).

Recommended optional programme components

♦ Opportunity to attend seminars and conferences relevant to solving problems. These include the international symposium organized by the Association for the Rehabilitation of Concrete Structures, as well as International Association for Science and technology of building Maintenance and Monuments Preservation etc.

Recommended or required reading

Not applicable.

Planned learning activities and teaching methods

♦ The content of the lectures is prepared in the digital form of presentations with the largest share of graphic details that will allow to closer understanding the objective issue. The content of exercise lectures is based on the digital presentation of task, which is then clearly undertaken by experiment and then student must compile and evaluate the results in the reports.

Assesment methods and criteria linked to learning outcomes

♦ Attendance at seminars is compulsory. During the exercise students work protocols, protocols of the working groups, some individually. Elaboration the final test min. 65% success rate. The course ends with an examination which is compulsory written and oral. To proceed to the oral is necessary to obtain at least 25 points (max 40) to pass the exam then at least another 15 in the oral part.

Language of instruction

Czech

Work placements

♦ Internship opportunities as well and collaboration with renowned foreign institutions renowned in the field, such as Vienna University of Technology, National university of Kyiv etc.

Course curriculum

1. Formulation of basic notion in the field of lifetime building materials (divided to physico-mechanical and physico-chemical influences).
2. Physilco-mechanical influences (effects of moisture, freeze, loading etc.).
3. Evaluation of particular sort of corrosive conditions and their influence on building materials (gaseous media).
4. Evaluation of particular sort of corrosive conditions and their influence on building materials (liquids).
5.-7. Mechanism of concrete deterioration and corrosion of reinforcement (corrosion of steel elements in concrete, genesis of cracks, peeling, calcareous and magnesium expansions, sulphate attack, etc.).
8. The basic principles of protection building materials.

Aims

Introduction to the problems of lifetime building constructions especially from the view of reasons of failure genesis and selection of suitable building materials. Lessons are focused on basic notions in area of lifetime and durability of building materials. There are mainly discussed the major building materials of nowadays (reinforced concrete, ceramics, wood constructions etc.). The problems with degradation of these materials by physical-mechanical and physical-chemical influences are described in details.

Specification of controlled education, way of implementation and compensation for absences

Extent and forms are specified by guarantor’s regulation updated for every academic year.
