Mechanical Properties of Glass-Based Geopolymers Affected by Activator and Curing Conditions under Optimal Aging Conditions

Inorganic polymeric materials react slowly at room temperature and therefore, usually require high-temperature curing. This study determined the correlation between duration in The results revealed optimal values for each alkali equivalent of an activator (weight ratio Na2O/glass powder), curing temperature, duration. Increasing had positive effects when was lower than percentage. However, over-curing resulted visible cracking specimens. Furthermore, despite being initially high, compressive strength specimens gradually diminished after standing air. To ensure durability glass-based geopolymers, should not exceed 70 °C, 1 day, respectively.
