Determination of masonry modulus of elasticity in the direction of bed joints
Kuchař, Martin ; Klusáček, Ladislav (referee) ; Terzijski, Ivailo (advisor)
The determination of strain properties of masonry in the direction parallel to bed joints is a fundamental pre-requisite for designing structures, where masonry is subjected to horizontal stresses (e. g. strengthening with prestressing). The diploma thesis summarized techniques of determination of masonry modulus of elasticity presented in available literature. The goal is to suggest suitable methodology of determination of masonry modulus in direction parallel to the bed joints. In the practical part of the diploma thesis is that methodology verified by experimental test and results of tests are analyzed and discussed.

Development of masonry systeme for simple construction of internal masonry structures
Lidmilová, Klára ; Dobiáš,, Jiří (referee) ; Zach, Jiří (advisor)
The diploma thesis deals with the development of a new masonry system, for the production of which recycled brick could be used as a secondary raw material. In the field of literary research, the work deals with the methods of construction of vertical structures, the possibilities of lightening concrete, the life cycle of building materials and the use of secondary raw materials in construction. In the practical part, a masonry system was designed based on market research in the field of internal non-load-bearing masonry structures and requirements for these structures. In order to achieve these properties, concrete was chosen as the material for its production, where recycled brick was used as an alternative aggregate. As it is supposed to be a system for precise masonry, the material was compacted by vibrocompression. At the beginning, recipes were designed to verify the basic properties of concrete: density of hardened concrete, compressive strength and tensile bending strength, then other properties such as thermal conductivity and sound absorption coefficient were tested on improved recipes. Lightening and dimensional modules have been modified to achieve optimal properties. This was followed by a proposal for the method of masonry and surface treatment of a wall. Finally, the economic and environmental aspects of the masonry system were evaluated.

Development of advanced masonnry blocks for acoustic masonry construction
Lidmilová, Klára ; Horský, Antonín (referee) ; Zach, Jiří (advisor)
This thesis deals with study of sound behaviour in the field of partition structures, especially inter-residential partitions, evaluation of structures in terms of acoustic insulation properties and the production of ceramics in general and acoustic masonry elements. Based on a literature search and market research, new ways of solving acoustic-insulating masonry, including construction, were proposed. The feasibility of construction was verified on a small-scale model created using 3D printing. The selected masonry element was further developed into various dimensional modules, which were compared on the basis of the weights of the individual elements and on the basis of the number of joints. Furthermore, the levels of lightening of the elements were adjusted in order to achieve the highest possible values of the basis weight of the masonry and thus the highest possible airborne sound insulation.
