Course detail

Physics of Building Materials

FAST-BJA009Acad. year: 2024/2025

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.

Aims

Theory of physical and utility properties of building materials in the state of placing into building structures, interaction of used building materials with surrounding materials. Physical effects of building structures oriented on heat technical problems of buildings, moisture propagation in buildings, formation of internal microclimate, effect on environment, utilization of alternative heat sources, heat demand of building
The student would manage the goal of the subject by acquiring the knowledge on the theory of physical and end-use properties of construction materials in the state of incorporating them into the building structures, interaction of used building materials with surrounding materials, physical exposure of building structures with the focus on heat engineering of buildings, moisture diffusion in buildings, creating of internal microclimate in buildings, impact on the environment, use of alternative heat sources and heat intensity of buildings.
