Abstract

Hidratacija cementa predstavlja složen kemijski proces tijekom kojeg dolazi do vezanja vode s česticama cementnog praha. Najčešće korišteni cement u građevinskoj industriji je portland cement, čiji klinker sadrži četiri osnovne faze: alit, belit, aluminatnu i feritnu fazu. Sva četiri minerala sudjeluju u fazi hidratacije, a kao nusprodukt oslobađa se toplina poznata kao toplina hidratacije. Osnovna svojstva hidratacije cementa uključuju povećanje čvrstoće, postupno stvrdnjavanje, formiranje strukture pora i volumenske promjene. Osim toga, na hidrataciju cementa može značajno utjecati vodo-cementni omjer, temperatura i prisutnost aditiva. Hidratacija cementa ima ključnu ulogu u proizvodnji trajnih i sigurnih građevinskih materijala te igra značajnu ulogu u izradi betona i drugih građevinskih elemenata.

Abstract (english)

Hydration of cement represents a complex chemical process during which water binds to particles of cement powder. The most commonly used cement in the construction industry is portland cement, whose clinker consists of four primary phases: alite, belite, aluminate, and ferrite phases. All four minerals participate in the hydration phase, and as a byproduct, heat is released, known as heat of hydration. The fundamental properties of cement hydration include increased strength, gradual setting, pore structure formation, and volumetric changes. Additionally, factors such as the water-cement ratio, temperature, and the presence of additives can significantly influence cement hydration. Cement hydration plays a crucial role in the production of durable and safe construction materials and is a significant factor in the production of concrete and other construction elements.
