Entry Knowledge
The knowledge of general and physical chemistry. The basic knowledge in branch of physics in building engineering. The basic knowledge in silicate chemistry.
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.
The student would manage the goal of the subject by acquiring knowledge on key modern materials, mainly on reinforced concrete, ceramic products, wooden structures etc., by acquiring information on the problems of degradation of these materials by acting of physico-mechanical actors (i.e. mainly by frost disturbance, effects of increased temperature, etc.) and physico-chemical factors (i.e. mainly by different types of chemically aggressive environments).
