Physics of Building Materials
FAST-0J4Acad. year: 2019/2020
The subject contents is divided into three parts. The part of physical properties of materials, of building mechanics and of the moisture propagation. Further to getting knowledge for students the theory of this subject is extended to general information of physics, knowledge of building materials using some mathematical procedures. In the subject PBM especially the theory of heat transfer, of vapour diffusion and of humidity propagation and the air penetration through the structure of building materials is discussed with respect to the specific properties of this materials. Included is the non-homogenous arrangement in building fragments under steady and dynamic influence of the surroundings. By general principles of heat and moisture transfer the standard evaluation criteria of building structures are explained. The main principles of building structures and buildings proposals are included as well. The program of the subject contains chapters concerning experimental possibilities of the determination of material properties of building materials, the documentation of standard and binding properties for the proposal. The exercise has partly a laboratory and partly a calculation character.
