dc.description.abstractThe present study investigates the role of Al in the evolution of the crystalline phases of an alkali-activated binder. Samples were synthesized corresponding to the binder composition with various $Al_2O_3/Na_2O$ and MgO/binder ratios in hydrothermal condition. Thermodynamic modelling was carried out to predict the effect of the Al content in the binder composition on the formation of Al-bearing phases. The test results showed that an increasing Al content led to the alteration of the predominant zeolitic crystalline phase in the alkali-activated binder. In addition, MgO incorporation enhanced the reaction degree of hydration in the alkali-activated system and the crystal growth, specifically hydrotalcite-like phase. Consequently, the formed reaction products had a great effect on the pore characteristics of the alkali-activated binder given their variations in the crystal structure.-
