Description:

Subject gives information on principles of designing and development of new types of materials having directed properties for specific building applications and structures.

Contents:

Recognition of basic principles of formation of building materials structure that is in relation with material performance and properties.
Information on structure of substances, chemical, physical and physical-chemical bonds.
Material properties with respect to material structure.
Problems of rheological, physical, chemical and biochemical degradative processes in building materials, their cohesive and adhesive behaviour and molecular structures and bonds.
Most often used building materials and possibilities of the directed change of their properties.
