Evaluation of lime properties
Palušáková, Stanislava ; Beranová, Denisa (referee) ; Opravil, Tomáš (advisor)
This thesis deals with the evaluation of the properties of limes, which are used in the field of heritage preservation of monuments, but also for common construction applications. The aim of this thesis is to draw up the appropriate set of analyzes that suffice the necessary minimum for the evaluated characteristics of air limes. Based on the results obtained in this set it will be characterized analysed lime and recommended it for a specific application. For simple solution of this work we have to deal with using traditional commercially available lime CL 90, CL80 and CL70. Selection of appropriate characteristic analysis was based on CSN EN 459.

The possibilities regulation of production hydration heat of concrete with plasticizer
Hermann, Radek ; Halas, Vladimír (referee) ; Sedlmajer, Martin (advisor)
This thesis studies the problematics of water reducing and high range water reducing admixtures and their influence on the process of hydration of cement pastes. The process of hydration is examined in this thesis both in terms of hydration heat and hydration temperature rise. Attention is also paid to the influence of plasticizers in combination with retarding admixture regarding rheological properties of modified fresh cement pastes and their mechanical properties after 3 and 7 days from mixing.

Apartment building in the gap site
Doupovec, Vojtěch ; Pulec, Vladimír (referee) ; Perla, Jan (advisor)
The diploma thesis is focused on design of a monolithic reinforced concrete structure of an apartment building situated in a gap site. The foundation is designed on a foundation slab supported by piles, which together with the walls in the basement are made as a waterproofness concrete structure. It is a two-way wall construction system, made in a combination of masonry and reinforced concrete. The structure was assessed for the ultimate limit state and the serviceability limit state. Due to the requirement for waterproofness, the reinforcement was designed for non-force effects at an early stage. The work includes drawings of shapes and reinforcement.
