Course detail
Durability of Building Materials
FAST-CJ07Acad. year: 2013/2014
Introduction to problems of corroded constructions especially with respect to failure reasons, kinds of corrosive surroundings, selection of suitable building materials. The courses are concentrated especially to clear the microstructure and mechanical changes during corrosion, corrosion of reinforced concrete caused by aggressive surroundings and classification of materials according to durability. Corrosion of concrete, metals and building materials by liquid and gaseous media, different types of water corroding reinforced concrete structures are discussed in details and the influence of solid matters, mineral fats and oils etc. are discussed as well. This is followed by discussion of surface treatment improving the building structures resistance against aggressive effects and of impregnating concrete by plastic materials respectively, spraying of concrete by macromolecular substances, painting compositions based on water glass etc. Finally the possibility of building materials durability prognosis and the methods of building materials durability determination and possibilities of their protection are discussed.
Lectures are supplemented by laboratory exercises.

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 in detail the methodological approaches to durability testing of building materials and apply them in practiceo,
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
knowledge of possibility of plastics added into cement mortars and concrete,Theoretical and Technological Fundamentals of Inorganic Building Binders,the chemistry and technology of plaster, lime and cement manufacture. Basic knowledge necessary for the task to design composition of concrete with demanded final properties, the basic properties of input raw materials for concrete manufacture and the testing methods.General overview of ceramic raw materials properties, their processing, shaping methods in ceramics, drying, burning, properties of burnt body.
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.).
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.
