Height infulence of rheometer's inner cylinder on measured rheological properties of mortars |
Sekundarni povzetek: |
In this thesis we determined the influence of the inner cylinders height of the rheometer on the measured rheological properties of fresh mortar. For this purpose we used three different types of mortar, which were based upon the same cement CEM II/A - M (LL-S) 42,5 R. With the apparatus we tested three mortar types, each with is own admixture; with hyperplastificizer, with viscosity modifiying agent and withouth admixtures. Additionaly, we used the rheometer to test two different oils that are used to calibrate the rheometers in order to compare the results obtained on mortars with those obtained on material with known viscosity. |

Povzetek (ePrints): |
V diplomski nalogi smo ugotavljali vpliv višine notranjega valja reometra na izmerjene reološke lastnosti svežih malt. V ta namen smo uporabili tri različne vrste malt, ki so vsebovale enak cementu, CEM II/A - M (LL-S) 42,4 R. V reometru smo tako preizkusili malto z dodatkom hiperplastifikatorja, sredstva za kontrolo viskoznosti ter malto brez dodakov. Dodatno smo reometer uporabili za preizkus na dveh različnih oljih, ki se uporablja za kalibracijo reometrov, da smo lahko primerjali rezultate malt z rezultati materiala, katerega viskozne lastnosti so znane. |
