Sažetak
Calcium aluminate cement (CAC) is very versatile special cement. It is advantageously employed with high performance in specific applications when: resistance to chemical attack, high early strength, refractory, resistance to abrasion, and/or low ambient temperature placement is required. During the setting and hardening, microstructure of material and amounts of certain phases (hydraulic cement minerals, water and formed hydrates) are changing. The hydration of CAC is highly temperature dependent, yielding morphologically different hydrates that alter material properties. Knowledge of the hydration reactions and microstructure evolution is important from the viewpoint of safe usage, good durability and functionality. This paper presents a model of volume fraction evolution of reactants and products in CAC hydration process. The hydration of samples of commercial CAC ISTRA 40 (manufactured by: Istra Cement, Pula, Croatia) had been investigated at several temperatures under sealed and saturated conditions. Also, water to cement ratio was varied. The composition of cement and hydrates formed had been investigated by powder X-ray diffraction (XRD). Chemically bond water in the cement samples was determined by loss on ignition. The model predictions are compared to experimental results.
