Development of the anchor expansion silicate based material with thermal resistance
Müller, Jiří ; Bydžovský, Jiří (referee) ; Drochytka, Rostislav (advisor)
The research conducted focused on studying the development of expansive, silicate based- anchor materials that were resistant to high temperatures. The results showed that shrinking is a critical property as volume can change (mainly cause shrinkage) the anchoring materials. This can ultimatly lead to a collapse of a loaded connection. The aim of the study was to summarizing products on the market, to develop the development of anchor matters alone and methodology for testing. Selected were directly related to expansion and thermal resistence.

Chemical wall clamp based on fast-setting geopolymeric binders
Novotný, Radoslav ; Kalina, Lukáš (referee) ; Šoukal, František (advisor)
The aim of this work is to develope fast-setting geopolymeric binders applicable in the chemical wall clamp. This clamping systems are big trend because of easy application, ability to transfer big forces and short setting time. Binders of this systems are based on polymeric resin. Their raw materials are expensive, toxic and flammable substances. Based on this consideration an anorganic fast-setting geopolymeric binder was developed. This binders consist of mixture of metakaolin and precipitated silica activated by potassium hydroxide. Binder were characterized by suitable analytic methods (XRD, SEM, DTA). The results of this metods were used for optimalization of binder properties.
