Thermodynamic Stability of Thaumasite
Pospíšilová, Klára ; Dvořák, Karel (referee) ; Fridrichová, Marcela (advisor)
This work deals with the resolution of the identification characteristics of the thaumasit, which falls into the same group of AFt phases as the mineral ettringit. Both of these stages have the same structural arrangement and the morphology. This work’s specific goal is the synthetic preparation of thaumasit in a variety of conditions and its evaluation.
Studying the impact of mixed cement, limestone in particular, the properties of fresh and hardened concrete
Jarolím, Tomáš ; Horák, Ota (referee) ; Hela, Rudolf (advisor)
This thesis focuses on collecting all available data on mixing Portland cements and especially on Portland cements with limestone. In the experimental part are compare the rheological properities of mixing Portland cements with limestone, their compatibility with plasticizing additives, witch depends on the type of additives, dosage and time, then in experimental part they are summarized monitoring of physical-mechanical properties and volume changes of concrete.
