Study of properties of concrete with "green cement"
Matyk, Tomáš ; Dorazilová, Irena (referee) ; Bodnárová, Lenka (advisor)
The thesis focuses on collecting available information about possible ways of using and usage restriction of portland blended cements and portland cements with limestone for production of concrete. The experimental part of the thesis describes the behavior of portland blended cements and portland cements with limestone in aggressive environments. Furthermore, the thesis concerns the dependence of rheological properties of cement pastes of portland cements and portland cements with limestone on type of plasticizing additives.
Design of mixing ratio of two quarried aggregates fraction 0/4 mm for readymix concrete
Jastrzembská, Alena ; Dorazilová, Irena (referee) ; Bodnárová, Lenka (advisor)
This diploma thesis describes with mixing ratio of two kinds of small quarried aggregate for the production of ready mix concrete. The theoretical part summarizes the requirements of Czech technical standards to individual components of concrete, particularly the requirements for fine aggregates. In the practical part were designed the recipes for three classes of concrete and was done checking the properties of concrete in fresh and hardened state. Based on the results were determined the optimal mixing ratio of fine aggregate from location Smiřice and Lípa.
