- 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. |
