Abstract
U ovom radu odreĊivano je vrijeme poĉetka i kraja vezivanja cementa CEM I (Ultimo) pomoću Vicatova aparata i konduktometrijskom metodom. Korišteni cement komercijalni je proizvod tvornice „Cemex“ iz Kaštel Sućurca i to je portlandski cement s udjelom 95 – 100 % klinkera. Najprije je odreĊena normalna konzistencija cementne paste Vicatovim aparatom prema HRN EN 196-3:2016. OdreĊeni vodocementni omjer koji zadovoljava normalnu konzistenciju cementne paste je V/C NK = 0,275. Za cementne paste pripremljene uz V/C = 0,275, 0,285 i 0,50 odreĊeno je vrijeme poĉetka i kraja vezivanja Vicatovim aparatom te poĉetak vezivanja elektrokemijskom metodom odreĊivanjem specifiĉne elektriĉne provodnosti. Maksimalna vrijednost specifiĉne elektriĉne provodnosti odgovara poĉetku vezivanja. Podatci su obraĊeni i prikazani tabelarno i grafiĉki te su usporeĊeni s obzirom na vodocementni omjer i metode odreĊivanja.
Abstract (english)
In this work, the start and the end of CEM I (Ultimo) cement setting time was determined using a Vicat apparatus and the conductometric method. The used cement is a commercial product of the cement plant "Cemex" from Kaštel Sućurac and it is a Portland cement with a share of 95 – 100 % clinker. First, the normal consistency of the cement paste was determined with a Vicat apparatus according to HRN EN 196-3:2016. The specific water-cement ratio that satisfies the normal consistency of the cement paste is V/C NK = 0.275. For cement pastes prepared with V/C = 0.275, 0.285 and 0.50, the start and the end of setting time was determined with a Vicat apparatus and the start of setting time with the electrochemical method by determining the specific electrical conductivity. The maximum value of specific electrical conductivity corresponds to the beginning of setting time. The data were processed and presented in tables and graphs and compared with respect to water- cement ratio and determination methods.
