abstract / sažetak
In cementitious composites, the hydration process is the most important feature. The conditions, rate, and general manner of this process affect the properties of composites both at early and later ages. The development and prediction of future properties can be studied using both destructive and non-destructive methods to predict the potential and behaviour at later ages. Due to the early occurrence of autogenous shrinkage and the large influence of chemical shrinkage, the hydration process and the formation of the microstructure play an important role in determining the time zero point for autogenous shrinkage and the overall determination of the shrinkage value.
U cementnim kompozitima, proces hidratacije je najvažnija značajka. Uvjeti, brzina i opći način odvijanja procesa utječu na svojstva kompozita u ranoj i kasnijoj starosti. Razvoj i predviđanje budućih svojstava mogu se proučavati razornim i nerazornim metodama za predviđanje potencijala i ponašanja u kasnijoj dobi. Zbog rane pojave autogenog skupljanja i velikog utjecaja kemijskog skupljanja, proces hidratacije i formiranje mikrostrukture igraju važnu ulogu u određivanju nulte točke mjerenja autogenog skupljanja i ukupnom određivanju vrijednosti skupljanja.
