COURSE DESCRIPTION |
Course objectives |
Acquiring basic theoretical knowledge about the processes of decay and corrosion in the resistance and durability assessment of commercial inorganic non-metallic materials under natural conditions of their application |
Course enrolment requirements and entry competences required for the course |
Materials in cnstruction engineering, Corrosion and protection of metals |
Learning outcomes expected at the level of the course (4 to 10 learning outcomes) |
After passing the exam the student is expected to know: - Distinguish the mechanism of corrosion of metals and non-metals - Categorize the types of chemical corrosion of concrete, mortar and cement composites as a result of the interaction of concrete (mortar, cement composite) and aggressive environment - A model to explain the chemical action of seawater on concrete or reinforced concrete - Assess the impact of atmospheric corrosion and deterioration of technical and decorative stone - To predict the effects of alkali-aggregate reaction - Assess the impact of pozzolanic additives and other additives (for example, finely ground limestone) on the prevention of corrosion and improve the durability of concrete, mortar and cement composites - Explain the process of wear and / or corrosion of technical glass surface under the influence of atmospheric - Apply the methods of testing the impact of the aggressive environment on the durability of structures - Evaluate and propose protection measures in order to improve the durability of selected inorganic non-metallic materials. |

Grading and evaluating student work in class and at the final exam |
The entire test can be applied over two exams during the semester. Passing threshold is 60%. Each colloquium in assessing participates with 45%. Lectures presence of 80 to 100% is 10% marks. The examination periods there is a written and oral exam. Passing threshold is 60%. Passing one colloquium (previous activity) is true in the summer examination period with a share of 10% in the assessment. Written exam has a share of 40% and 50% verbal. Students who have not passed the exam by tests take the examination through written and oral exams in the regular examination period. Passing threshold is 60% and the examination form to participate in the evaluation by 50%. Rating: 60% -70% - satisfactory, 71% -81% - good, 82% -92% very good, 93% -100% - excellent. |
