The verification of durability of surface layer by pull-off testing
Fujačková, Hedvika ; Komárková, Tereza (referee) ; Kocáb, Dalibor (advisor)
The theoretical part of this bachelor's thesis defines the basic properties, categorization, and use of the individual components of concrete and presents the properties of fresh and hardened concrete, especially the tensile strength. Furthermore, the thesis addresses the problem of durability assessment of concrete, which depends directly on the quality of the surface layer. The experimental part of the thesis focuses on executing of a pull-off test and examines the surface layer tensile strengths of various concrete mix designs. The thesis examines how the results of the measurements correspond with other published results.

SCC with secondary raw materials
Ťažká, Lucia ; Ťažký, Tomáš (referee) ; Hela, Rudolf (advisor)
Bachelor thesis is focused on the possibility of using secondary raw materials and their application to the production of SCC. Large part deals with impurities of type I and its application results mainly from abroad. Furthermore, this work examines the impact of different types of impurities on the resulting concrete durability in various aggressive environments. The practical part is focused on the use of chemically non-reactive additives of type I instead of the commonly used additives of type II which are used to replace part of cement and the resulting design and manufacture of low-strength SCC using appropriate additives.

High-valueable gypsum binder based on secondary raw materials
Rybová, Alexandra ; Dvořák,, Karel (referee) ; Fridrichová, Marcela (advisor)
The thesis is oriented on preparation of high – valuable gypsum binder using secondary raw materials with emphasis on technological properties and their improvement by aplication of selected modifier aditives. The first part of the task is dedicated to a teoretical knowledge in the field of gypsum binders, especially to the raw materials, properties and possibilities of utilization. Second part is focused on experimental works that test properties of gypsum and effectivness of selected modifier aditives.
